[0001] This application claims the benefit of U.S. Provisional Application No. 63/088,600, filed October 7, 2020, and U.S. Provisional Application No. 62/965,681, filed January 24, 2020, each of which is incorporated herein by reference in its entirety.

BACKGROUND

[0002] Polyurethanes (PU) can be produced via the condensation of a hydroxyl functionality, such as a polyol, with an isocyanate moiety. As a polymer class, polyurethanes are quite diverse and unique among plastics as the chemical structure of polyurethanes is not a highly repetitive unit. As a consequence, polyurethanes having the same general physical properties can have dramatically different chemical compositions. Because of their diverse structural makeup, polyurethanes come in myriad forms and are used for the production of resins, films, coatings, hard and soft foams, sealants, adhesives, and elastomers.

[0003] Most polyols are typically derived from petroleum feedstocks. However, as the global climate continues to warm, and with little doubt remaining as to the direct correlation between the increased utilization of fossil fuels over the past millennium and the imminent threat posed by a warming climate, there is an urgent need to replace incumbent, petroleum derived fuels and chemicals with more sustainable, renewable materials. The polyol components of polyurethanes present an opportunity for renewable alternatives with novel functionalities.

DETAILED DESCRIPTION

[0018] Provided herein are methods for generating polyols from microbial derived oils having some degree of unsaturation. These polyols can subsequently be reacted with an isocyanate to generate a polyurethane. Polyurethanes can serve as excellent thermoset resin materials because of their pourability at room temperature. Because these polyurethanes are a fluidic state at room temperature, they do not require melting prior to incorporating into a component of a final product. Depending upon formulation, curing of polyurethane resins can be accomplished at room temperature, with the addition of heat or light, or with addition of a curing agent. Microbial derived, pourable thermoset resins, alone or in combination with other materials, can have a variety of material applications in consumer goods, such as skis, snowboards, skateboard, surfboards, paddleboards, wakeboards, kiteboards, and split boards. [0019] As used herein, the term “hydroformylated” or “hydroformylation” refers to the sequential chemical reactions of hydroformylation (across C=C double bonds) to produce an aldehyde, followed by hydrogenation (of the resulting aldehyde) to produce an alcohol unless indicated otherwise.

Construction of Skis and Other Sporting Goods Equipment

[0033] Skis, snowboards, and other sporting goods equipment can be composed of a core material surrounded by a top layer and a bottom layer, and reinforced by sidewalls.

[0034] The top layer can be composed of layers of plastic and/or fibrous materials, for example, wood, fiberglass, carbon fiber, Kevlar, flax, hemp, or wool.

[0035] The bottom layer can be composed of layers of plastic, polyethylene, fiberglass, as well as elastomeric materials. Non-limiting examples of elastomeric materials include polyethylene, rubber, and neoprene. The bottom layer includes a base layer, which can be composed of polyethylene with a metal edge. Non-limiting examples of metals include steel, titanium, aluminum, and an alloy thereof. In some embodiments, the metal edge is composed of steel with a Rockwell Hardness in the range of HRC 45-60. A layer of elastomeric material can sit atop the metal edge, which can help dampen vibrations arising from the metal. In some embodiments, the base layer does not include a metal edge. The sidewall can refer to an area along the edge of a ski above the metal edge that laterally reinforces the core material. [0036] FIG. 1, Panel G illustrates a cutaway view of an example ski having an example algal polyurethane composite core. The top sheet (a) is a plastic-like material, including, but not limited to, thermoplastic, polyurethane, ABS, TPU/ABS co-polymer, high molecular weight polyethylene, nylon, and polybutylene terephthalate (PBT). Below top sheet a is one or more layers of fiberglass or other fibrous material, such as plant or animal derived fibers (b). Fiber types include, for example, flax, hemp, and wool. The following core composite layer is the algal PU wood composite (c and d), which is flanked by two algal cast PU sidewalls (h). The composite core is underpinned by one or more additional layers of fiberglass or other fibrous material. The base layer or bottom sheet (e) is composed of polyethylene. The base layer also includes a metal edge (g). A layer of elastomeric material (f) sits atop the metal edge and functions to dampen vibrations that arise from the metal. The elastomeric material can be composed of rubber or neoprene.

[0037] The core material can be composed of various materials, including wood and a hydrophobic material overlaid with fiberglass and a resin that provides strength and rigidity. The resins can be an epoxy based resin or a polyurethane resin. In some embodiments, the resin is a cast polyurethane resin derived from microbial oil. In some embodiments, the core material of a sporting goods equipment described herein can be a composite material containing polyurethane foam and a solid material. The composite material can be composed of alternating layers of polyurethane foam and a solid material. A solid material can be a plastic, a fibrous material, a metal, an elastomeric material, or a thermoset material. Non limiting examples of plastic include polyurethane, polyethylene, and thermoplastic. Non limiting examples of metals include steel, titanium, aluminum, or an alloy thereof. Non limiting examples of a fibrous material include wood, fiberglass, carbon fiber, Kevlar, flax, hemp, or wool.

[0038] In some embodiments, the core material is composed of polyurethane and one of more species of wood. Wood varieties vary in weight, strength, and flexibility. For example, paulownia is ultra-lightweight, but tends not to dampen vibrations as well as other woods. Beech, maple, ash and fir, for example, are denser and burlier than other types and thus, provide great torsional rigidity and stability. Non-limiting examples of wood types include paulownia (for example, Paulownia sp.), cherry (for example, Prunus sp.), birch (for example, Betula sp.), alder (for example, Alnus sp.), fuma (for example, Ceiba sp.), ash (for example, Fraxinus sp.), box elder (for example, Acer negundo), chestnut (for example, Castanea sp.), elm (for example, Ulmus sp.), hickory (for example, Carya sp.), koa (for example, Acacia sp. and Acacia koa), mahogany (for example, Swietenia sp.), sweetgum (for example, Liquidambar sp.), oak (for example, Quercus sp.), ash (for example, Fraxinus sp), aspen (for example, Populus tremuloides), beech (for example, Fagus sp , maple (for example, Acer sp), poplar (for example, Populus sp), walnut (for example, Juglans sp), pine (for example, Pinus sp), cedar (for example, Cedrus sp. and Libocedrus sp), yew, fir (for example, Abies sp), Douglas fir (for example, Pseudotsuga menziesii), larch (for example, Larix sp), hardwood, bamboo (for example, Bambusoideae sp), blackwood, bloodwood, basswood, boxelder, boxwood, brazilwood, coachwood, cocobolo, corkwood, cottonwood, dogwood, ironwood, kingwood, lacewood, marblewood, sandalwood, rosewood, zebrawood, ebony, ivory, buckeye, satinwood, kauri, spruce (for example, Piceasp), cypress (for example, Taxodium sp), hemlock (for example, Tsuga sp , redwood (for example, Sequoia sp. and Sequoiadendron sp.), rimu, teak (for example, Tectona sp.), eucalyptus, and willow (Salix). In some embodiments, the core material is composed of polyurethane and paulownia. In some embodiments, the core material is composed of polyurethane and aspen. In some embodiments, the core material is composed of polyurethane, paulownia, and aspen.

[0039] In some embodiments, the composite material can be composed of alternating strips of wood and polyurethane foam that are longitudinally layered along the length of the strips. Each strip can be affixed to one another by an adhesive or bonding material. Non-limiting examples of adhesives include a polyvinyl acetate based adhesive, an ethylene vinyl acetate based adhesive, a polyurethane based adhesive, a urea-formaldehyde based adhesive, a melamine based adhesive, and a silicone based adhesive. In some embodiments, the strips of a composite can be laminated together with a resin and/or heat. The resin can be an epoxy resin.

[0040] In some embodiments, the core material can be comprised entirely of wood.

[0041] In some embodiments, the core material can be comprised entirely of polyurethane foam.

[0042] In some embodiments, a polyurethane foam can contain a polyol derived from algal oil.

[0043] Heavy skis can be unwieldy and reduce the responsiveness and utility in many applications of these equipment. For example, backcountry skiers or ski mountaineers must ascend on skis using their own locomotion, often for several thousand vertical feet, in difficult terrain to attain sufficient altitude from which to descend. Thus, lightweighting can be a critical factor in the design of high quality and functional ski equipment.

[0044] Solid wood cores made of glue-laminated lamellae are commonly used in ski core equipment. Solid wood cores provide desirable strength and flexural (bending) properties, and come in a variety of types, grains, and densities. Flexural properties are defined as the ability to resist fracture, as described, for example, in ASTM D790. Lamination of wood strips that differ in density and strength allows for optimization for strength and weight of the lamellae.

[0045] Sidewalls can provide protection and support to the core of a sporting goods equipment. The sidewall of sporting goods equipment serves as an impervious barrier to the elements and prevents ingress of elements to the core material. Ingress of elements to the core material of a sporting goods equipment is a main contributor to deterioration and mechanical failure of the equipment. Thus, the construction and composition of the sidewall material are critical to the proper functioning and maintenance of sporting goods equipment.

[0046] The sidewall barrier is particularly important for backcountry ski applications. Backcountry skiers often ski solo over open and rocky terrain, and heavily depend on the durability of the skis. Thus, sturdy sidewall materials are required for practical applications of backcountry skis.

[0047] Additionally, the strength of the sidewall is critical at the area underfoot, at the edge of the ski. During cornering and breaking, the ski edge, and by extension, the sidewall, experience the greatest load as the skier’s weight and the associated force exert maximal force on the ski edge.

[0048] Typically, ski sidewall materials are composed of ABS (acrylonitrile butadiene styrene), UHMWPE (ultra-high molecular weight polyethylene), or HDPE (high density polyethylene). These materials are received as strips or sheet stock, and then cut to the appropriate dimensions for incorporation into the ski. This method can be more laborious and results in the accumulation scrap materials, which can be wasteful and environmentally unsustainable.

[0049] An alternative method of creating sidewall material is using a pourable polyurethane. Pourable polyurethane allows for assembly of sidewalls and other materials using the wooden ski core as a mold, and thereby obviates the cutting step prior to assembly of a final product.

In some embodiments, the pourable polyurethane is derived from microbial oil, for example, an algal oil. Utilization of a cast urethane sidewall material with an algal derived polyol affords the opportunity to create myriad formulations that cannot be obtained with other products whose physical properties are fixed. In addition, utilization of a cast urethane and its incorporation as a sidewall material allows for control of the depth and thickness, both of which can impart performance properties on the finished ski while minimizing the amount of material used.

[0050] Unlike incumbent materials, such as ABS, UHMWPE, or HDPE, a pourable polyurethane provides the additional benefit of forming an intimate bond with an adjacent wood core. The free hydroxyl groups present in the cellulosic wood core bond to free isocyanate groups in the polyurethane, thereby forming covalent bonds with the polymer network. Incumbent materials, on the other hand, require the application of a separate adhesive such as an epoxy, for example, to adhere to the wood. [0051] From a sustainability and greenhouse gas (GHG) emissions perspective, incumbent sidewall materials made from petroleum-based, non-renewable, and net GHG emitting materials, such as ABS, UHMWPE, and HDPE, are not ideal. Replacement of these unsustainable materials with a biobased, cast PEI material derived from renewable materials offers a solution to the shortcomings of conventional methods of polyurethane production. [0052] Using the cast urethane approach, the core material (FIG. 1, Panel A, top view) and (FIG. 1, Panel B, side view) is channeled (FIG. 1, Panel C, top view channel outline and FIG. 1, Panel D, top view channel outline overlaid on core) such that the core material serves as a mold to receive the pourable urethane. Final dimensions of the pourable urethane can be determined through planing and computer numerical control (CNC) routing. The resulting sidewall material is fully integrated with the profiled core (FIG. 1, Panel E). The uniform integration of the sidewall material and the core composite is attributed to reaction of the cast urethanes with the sugar moieties in the cellulose forming urethane linkages of the polyurethane composite. In addition, because the cast urethane is flowable prior to curing and/or setting, the cast urethane can follow into vessels (for example, in softwoods) and tracheids (for example, in hardwoods), thereby allowing for much greater penetration of the sidewall material into the core as compared to sidewall materials that are bonded to the core by the epoxy resins alone.

[0053] FIG. 1, Panel F illustrates side, profile and cross sectional views (at tip, waist and tail) of a core composite created with a cast urethane sidewall and showing the relative contribution of the cast sidewall material at each cross sectional area. FIG. 1, Panel G illustrates a cutaway view of an example ski composition, containing materials of construction including cast sidewall material. The components of the ski shown in FIG. 1, Panel G can be assembled, layer by layer, into a metal mold with the application of an epoxy resin and hardener.

[0054] The top sheet (a.) can be composed of one or more plastic-like materials including, but not limited to, thermoplastic polyurethanes (TPUs), ABS, TPU/ABS co-polymers, high molecular weight polyethylene, nylon, and polybutylene terephthalate (PBT).

[0055] The top sheet can be followed by one or more sheets of a fibrous material (b.). Non limiting examples of fibrous materials include fiberglass, carbon fiber, Kevlar, and plant or animal based fiber-based materials, for example, flax, hemp, and wool.

[0056] The bottom layer is typically comprised of a bottom sheet (e.) made of a variety of plastics, for example, high molecular weight polyethylene. For sporting goods equipment such as skis, splitboards, and snowboards, the base also contains a ski edge (g.), which is often comprised of metal. In some embodiments, the metal is steel with a Rockwell Hardness in the range of HRC 45-60. A layer of elastomeric material (f.) sits atop the metal edge and functions to dampen vibrations that arise from the metal. The elastomeric material can be composed of rubber or neoprene.

[0057] The components of the ski can be affixed together by an epoxy resin and assembled in a mold. In some embodiments, a sporting goods equipment or a component thereof can be assembled in a mold in the presence of heat, pressure, or both.

[0058] FIG. 1, Panel H illustrates side, profile, and cross sectional views (at tip, waist and tail) of a ski created with a cast urethane sidewall and showing the relative contribution of the cast sidewall material at each cross sectional area along with the other materials of construction shown in FIG. 1, Panel G.

Methods of Production

[0070] In some embodiments, a sporting goods equipment or component thereof can be produced by casting a polyurethane resin into a mold comprising a composite material such that the resin adheres to the composite material and takes on the shape of the mold. After casting, the polyurethane resin can be cured at a temperature of from 20 °C to 110 °C or from 20 °C to 25 °C, for example, at 20 °C, at 25 °C, at 30 °C, at 35 °C, at 40 °C, at 45 °C, at 50 °C, at 55 °C, at 60 °C, at 65 °C, at 70 °C, at 75 °C, at 80 °C, at 85 °C, at 90 °C, at 100 °C, or 110 °C. In some embodiments, the polyurethane resin can be cured at room temperature (e.g., about 25 °C). In some embodiments, the polyurethane resin can be cured at room temperature (e.g., about 25 °C) for at least 48 hours. In some embodiments, the polyurethane resin can be cured by heat. In some embodiments, the polyurethane resin can be cured at about 75 °C for at least 30 minutes. In some embodiments, the polyurethane resin can be cured at about 110 °C for at least 15 hours. In some embodiments, the polyurethane resin can be cured at a temperature that is not greater than 25 °C. In some embodiments, the polyurethane resin can be cured at a temperature that is not greater than 110 °C.

Cast urethane formulations can be characterized by various metrics, including tensile strength, elongation at break, flexural strength, break stress, glass transition temperature, Shore hardness, and biobased content. Some of these parameters can be assessed at various temperatures dependent upon the application of the polyurethane resin. For example, a polyurethane resin can be assessed at low temperature (e.g., 0-2 °C), room temperature (e.g, about 25 °C), or high temperature.

In some embodiments, elongation at break of a polyurethane resin is assessed by ASTM D638.

[0076] In some embodiments, the polyurethane resin has a flexural strength of about 2,000 psi to about 11,000 psi. For example, the polyurethane resin has a flexural strength of 2,000 psi or more, 2,500 psi or more, 3,000 psi or more, 3,500 psi or more, 4,000 psi or more, 4,500 psi or more, 5,000 psi or more, 5,500 psi or more, 6,000 psi or more, 6,500 psi or more, 7,000 psi or more, 7,500 psi or more, 8,000 psi or more, 8,500 psi or more, 9,000 psi or more, 9,500 psi or more, 10,000 psi or more, 10,500 psi or more, or 11,000 psi or more.

[0081] In some embodiments, a sporting goods equipment or component thereof can be produced in a heated press at a temperature ranging from 50 °C to 100 °C, from 50 °C to 60 °C, from 60 °C to 70 °C, from 70 °C to 80 °C, from 80 °C to 90 °C, or from 90 °C to 100 °C, for example, at about 50 °C, at about 60 °C, at about 70 °C, at about 80 °C, at about 90 °C, or at about 100 °C.

[0082] In some embodiments, a sporting goods equipment or component thereof can be produced in a pressurized mold ranging from about 20 psi to about 100 psi, from about 20 psi to about 30 psi, from about 30 psi to about 40 psi, from about 40 psi to about 50 psi, from about 50 psi to about 60 psi, from about 60 psi to about 70 psi, or from about 80 psi to about 100 psi, for example, at about 20 psi, at about 30 psi, at about 40 psi, at about 50 psi, at about 60 psi, at about 70 psi, at about 80 psi, at about 90 psi, or at about 100 psi.

[0083] In some embodiments, a sporting goods equipment or component thereof can be produced by application of heat and/or pressure for duration of from about 10 minutes to about 20 minutes, from about 20 minutes to about 30 minutes, from about 30 minutes to about 40 minutes, from about 40 minutes to about 50 minutes, from about 50 minutes to about 70 minutes, for example, about 10 minutes, about 15 minutes, about 20 minutes, about 25 minutes, about 30 minutes, about 35 minutes, about 40 minutes, about 45 minutes, about 50 minutes, about 55 minutes, 60 minutes, about 65 minutes, about 70 minutes, about 75 minutes, about 80 minutes, 85 minutes, 90 minutes, or more.

[0084] Ski sidewalls can be constructed in various configurations including, for example, cap construction, sandwich construction, half cap construction, and hybrid construction. Cap construction is where the top layer folds over the edges of the core material. Cap construction can be a lightweighting method by the omission of heavy sidewall materials running along the length of the ski. Sandwich construction involves layering of the top sheets, core material, and bottom sheets such that the integrated product resembles a sandwich configuration. The core material is not covered by the top layers, but instead flanked on each side by a sidewall. In some embodiments, the sidewalls are beveled, for example top beveled. Sandwich construction can provide increased power transmission to the edge of the ski, and thus, greater flexibility. Half cap (hybrid) construction is a fusion of cap construction and sandwich construction. In this configuration, the top layer folds over the edges of the top half of the core material, including the sidewalls. The bottom half of the core material is uncovered, but flanked on each side by a sidewall. Half cap construction provides the benefit of lightweight and adequate power transmission.

[0085] Skis and other similar sporting goods equipment can have various shapes, contours, and profiles that confer specific functional properties. For example, the width and/or height can vary along the length of the ski. Straight lines skis, or skis having the same width along the length, are more stable, but can making turning more difficult. FIG. 1, Panel C illustrates an example algal polyurethane composite core outline. In this example, the tip and tail of the ski are wider than the waist (middle) of the ski, and the profile is rounded. FIG. 1, Panel D illustrates the outline overlaid onto a wood-algal PU core (top view). FIG. 1, Panel E illustrates a side view of the wood-algal PU foam cores shown in FIG. 1, Panels C and D. [0086] The overall architecture of an example ski, including the sidewall material, is illustrated in FIG. 1, Panels F-H. The ski core material can have a variety of dimensions and configurations depending upon the precise needs of the designer. The ski core can also be composed of a variety of materials, including but not limited to, one or more wood species, a foam material, or a combination thereof. In some embodiments, the foam material is derived from microbial oils.

[0087] The precise order, length, and width of components of a composite material can be varied to suit the particular needs of the designer. In some embodiments, the composite material can have a length in centimeters (cm) of 50 cm to 250 cm, for example, about 50 cm, about 51 cm, about 52 cm, about 53 cm, about 54 cm, about 55 cm, about 56 cm, about 57 cm, about 58 cm, about 59 cm, about 60 cm, about 61 cm, about 62 cm, about 63 cm, about 64 cm, about 65 cm, about 66 cm, about 67 cm, about 68 cm, about 69 cm, about 70 cm, about 71 cm, about 72 cm, about 73 cm, about 74 cm, about 75 cm, about 76 cm, about 77 cm, about 78 cm, about 79 cm, about 80 cm, about 81 cm, about 82 cm, about 83 cm, about 84 cm, about 85 cm, about 86 cm, about 87 cm, about 88 cm, about 89 cm, about 90 cm, about 91 cm, about 92 cm, about 93 cm, about 94 cm, about 95 cm, about 96 cm, about 97 cm, about 98 cm, about 99 cm, about 100 cm, about 101 cm, about 102 cm, about 103 cm, about 104 cm, about 105 cm, about 106 cm, about 107 cm, about 108 cm, about 109 cm, about 110 cm, about 111 cm, about 112 cm, about 113 cm, about 114 cm, about 115 cm, about 116 cm, about 117 cm, about 118 cm, about 119 cm, about 120 cm, about 121 cm, about 122 cm, about 123 cm, about 124 cm, about 125 cm, about 126 cm, about 127 cm, about 128 cm, about 129 cm, about 130 cm, about 131 cm, about 132 cm, about 133 cm, about 134 cm, about 135 cm, about 136 cm, about 137 cm, about 138 cm, about 139 cm, about 140 cm, about 141 cm, about 142 cm, about 143 cm, about 144 cm, about 145 cm, about 146 cm, about 147 cm, about 148 cm, about 149 cm, about 150 cm, about 151 cm, about 152 cm, about 153 cm, about 154 cm, about 155 cm, about 156 cm, about 157 cm, about 158 cm, about 159 cm, about 160 cm, about 161 cm, about 162 cm, about 163 cm, about 164 cm, about 165 cm, about 166 cm, about 167 cm, about 168 cm, about 169 cm, about 170 cm, about 171 cm, about 172 cm, about 173 cm, about 174 cm, about 175 cm, about 176 cm, about 177 cm, about 178 cm, about 179 cm, about 180 cm, about 181 cm, about 182 cm, about 183 cm, about 184 cm, about 185 cm, about 186 cm, about 187 cm, about 188 cm, about 189 cm, about 190 cm, about 191 cm, about 192 cm, about 193 cm, about 194 cm, about 195 cm, about 196 cm, about 197 cm, about 198 cm, about 199 cm, about 200 cm, about 201 cm, about 202 cm, about 203 cm, about 204 cm, about 205 cm, about 206 cm, about 207 cm, about 208 cm, about 209 cm, about 210 cm, about 211 cm, about 212 cm, about 213 cm, about 214 cm, about 215 cm, about 216 cm, about 217 cm, about 218 cm, about 219 cm, about 220 cm, about 221 cm, about 222 cm, about 223 cm, about 224 cm, about 225 cm, about 226 cm, about 227 cm, about 228 cm, about 229 cm, about 230 cm, about 231 cm, about 232 cm, about 233 cm, about 234 cm, about 235 cm, about 236 cm, about 237 cm, about 238 cm, about 239 cm, about 240 cm, about 241 cm, about 242 cm, about 243 cm, about 244 cm, about 245 cm, about 246 cm, about 247 cm, about 248 cm, about 249 cm, or about 250 cm.

Polyurethane Production

[0103] Polyurethane can be produced by reacting isocyanates and polyols. Physical properties of polyurethanes can be influenced by the addition of chemical additives during processing. These physical properties include density, strength, and flexural properties, which are critical factors for the application of polyurethanes in consumer products. For example,

PU foam production requires a blowing agent (also known as a pneumatogen), a substance that creates holes in the foam matrix, thereby providing cellular structure to the foam. Blowing agents can be added in a liquid form during the hardening stage of the foam resulting in the formation of gaseous products and byproducts. Non-limiting examples of chemical blowing agents include isocyanate, water, cyclopentane, pentane, methylformate, dimethoxymethane, azodicarbonamide, hydrazine, and other nitrogen-based materials, and sodium bicarbonate.

[0104] In contrast, the reaction of isocyanate and polyol in the absence of a blowing agent yields a polyurethane resin, which can be used as a pourable cast material.

Polyols

[0105] Microbial oil produced by oleaginous microbes has numerous advantages, including, but not limited to, improved production efficiency and TAG compositions that can be enhanced for generating polyols. Namely, increasing the levels of unsaturation of TAG compositions can enhance control of the chemistry involved in the generation of polyols. These characteristics of microbial oil result in a greater yield of -OH functionality relative to other currently available oils with greater TAG heterogeneity (hence, lower purity) and/or diversity (e.g., oilseed or plant derived oils). Thus, polyols derived from a microbial oil can be preferable in generating polymers, including in instances where physical properties of a polymer can be compromised by molecular impurities, such as non-hydroxylated fatty acids, that may be present in oils comprising a more diverse and/or heterogeneous TAG profile. [0106] Methods of producing triglyceride oils from oleaginous microbes may also have reduced carbon footprints than methods of producing oils from cultivation of oilseeds. This may be particularly true when the sugar used for the cultivation of these microbes is sourced from energy efficient sugar cane mills that significantly rely on power supplied from co generation of sugarcane bagasse.

[0107] Polyols derived from a microbial oil may be particularly useful for producing polyurethane materials. For example, microbial oils may comprise relatively low TAG diversity, low fatty acid diversity, and the majority of fatty acids present in the microbial oil may be unsaturated fatty acids. A higher ratio of unsaturated fatty acid to saturated fatty acid allows for increased chemical reactivity at the double bonds. Microbial oils having low TAG diversity and a high proportion of unsaturated fatty acids are especially desirable in production of polyurethanes because hydroxylation of such a mixture yields a greater percentage of fatty acids that can participate in crosslinking reactions with isocyanates. Unlike unsaturated fatty acids, saturated fatty acids which do not contain carbon-carbon double bounds and cannot participate in crosslinking reactions with isocyanates. Thus, polyols generated from hydroxylation of unsaturated fatty acids from microbial oil may yield polyurethane materials having superior properties.

[0108] Polyols derived from highly unsaturated oils have high hydroxyl numbers compared to polyols derived from oils having lower saturation levels. High hydroxyl number increases the versatility of a polyol for producing a wide range of polyurethane materials. A polyol described herein can have a hydroxyl number of from 125 to 165, from 145 to 165, from 135 to 160, or from 140 to 155. For example, a polyol described herein can have a hydroxyl number of 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158,

159, 160, 161, 162, 163, 164, or 165. In some embodiments, the hydroxyl number of a polyol can be determined by ASTM El 899.

[0109] In the process of producing natural oil polyols (NOPs) from natural sources, the hydroxyl functionality can be introduced via a chemical conversion of the triglyceride oil. This conversion requires the presence of a double bond on the acyl moiety of the fatty acid, e.g., an olefmic group, which can be accomplished using several different chemistries including, for example:

[0110] i) Epoxidation in the presence of hydrogen peroxide and an acid catalyst, followed by ring opening with reagents, such as water, hydrogen, methanol, ethanol, propanol, isopropanol, C1-C4 carboxylic acids, or other polyols, e.g., acetic acid or formic acid. Ring opening can be facilitated by reaction with an alcohol, including, for example, b-substituted alcohols. These chemistries result in secondary hydroxyl moieties, and are therefore less reactive, for example, with isocyanate or methyl esters.

[0111] ii) Ozonolysis by molecular oxygen results in the formation of ozonides, which upon further oxidation results in scission at the double bond and formation of di-acids, carboxylic acids, and upon reduction with hydrogen, formation of aldehydes. Ozonolysis and reduction of oleic acid, for example, produces azaleic acid, pelargonic acid, and pelargonaldehyde, respectively.

[0112] iii) Hydroformylation with synthesis gas (syngas), using rhodium or cobalt catalysts to form the aldehyde at the olefmic group, followed by reduction of the aldehyde to alcohol in the presence of hydrogen.

[0113] While typically carried out in organic solvent, processes that utilize aqueous systems have been developed to improve the sustainability of these chemistries. Of the chemistries described above, only hydroformylation results in the preservation of fatty acid length and formation of primary -OH moieties. Furthermore, only olefmic fatty acids with a double bond that is converted into a site possessing hydroxyl functionality, either through epoxidation and ring opening, ozonolysis and reduction, or hydroformylation and reduction, can participate in subsequent downstream chemistries, i.e., reaction with an isocyanate moiety to form a urethane linkage or reaction with methyl esters to form polyesters. All other fatty acids, namely, fully saturated fatty acids that do not contain carbon-carbon double bonds, cannot participate in crosslinking reactions with isocyanates. Hence, saturated fatty acids will compromise the structural integrity and degrade performance of the polymer produced therefrom.

[0114] The complexity and physical properties of a triglyceride oil can be evaluated by the fatty acid profile, and the triacylglycerol (TAG) profile. The fatty acid profile is simply a measure of fatty acid composition. The fatty acid profile of a triglyceride oil can be determined by subjecting oils to transesterification to generate fatty acid methyl esters and subsequently quantitating fatty acid type by Gas Chromatography with Flame Ionization Detector (GC-FID).

[0115] Additionally, if the fatty acid profile can be modulated such that the concentration of a particular species of monounsaturated or polyunsaturated fatty acids can be significantly increased from the concentration in the native oil, there would be an overall decrease in the diversity of TAG species present in the resulting oil. The net effect is that a higher number of hydroxylated fatty acids and a higher proportion of all TAG species can participate in urethane chemistries. For example, in two cultivars of peanut oil, N-3101 and H4110, oleic acid content was increased from 46% to 80% and total monounsaturated and polyunsaturated fatty acids was increased only subtly, from 77% to 84%, respectively. According to the TAG profile of the resulting oils derived from the two cultivars, approximately 95% of all TAG species are accounted for in just eight regioisomers in cultivar H4110 and 23 regioisomers in cultivar N-3101. Thus, triglycerides that are significantly enriched in a single species result in more homogeneous substrates for subsequent chemical manipulations and incorporation into materials.

[0116] Provided herein are methods for the conversion of oils into highly homogenous polyols via hydroformylation and hydrogenation, as well as epoxidation and ring opening.

The molecular purity of these polyols can be advantageous for all types of polyurethane applications, including, but not limited to, as coatings for textiles and surfaces, as adhesives in packaging, textile, and industrial applications, as well as in hard and soft foam, and elastomeric applications.

Microbial Oils Microbes

[0117] Microbial oils described herein may comprise novel triglycerides derived from a microbe. Microbial oils may be produced using oleaginous microbes.

[0118] Oleaginous microbes can refer to species of microbes having oil contents in excess of 20% on a dry cell weight basis. These microbes are uniquely suited for generating highly pure, natural oil polyols (NOPs) with hydroxyl (-OH) functionality. Oleaginous microbes have also been proven extremely facile for genetic modification and improvement.

[0119] Indeed, these improvements can occur on time scales that are greatly accelerated relative to what can be achieved in higher plant oilseeds. Oleaginous microbes offer tremendous utility in generating large quantities of triglyceride oils in short periods of time.

In as little as 48 hours, appreciable oil production of about 30-40% oil (dry cell weight) can be obtained, whereas typical production requires 120 hours or more to achieve 70-80% oil (dry cell weight).

[0120] Furthermore, because these microbes can be heterotrophically grown using simple sugars, the production of these triglyceride oils can be divorced from the traditional constraints imposed by geography, climate, and season that constrain triglyceride oil production from oilseed crops.

[0121] Recombinant DNA techniques can be used to engineer or modify oleaginous microbes to produce triglyceride oils having desired fatty acid profiles and regiospecific or stereospecific profiles. Fatty acid biosynthetic genes, including, for example, those encoding stearoyl-ACP desaturase, delta- 12 fatty acid desaturase, acyl-ACP thioesterase, ketoacyl- ACP synthase, and lysophosphatidic acid acyltransferase can be manipulated to increase or decrease expression levels and thereby biosynthetic activity. These genetically engineered microbes can produce oils having enhanced oxidative, or thermal stability, rendering a sustainable feedstock source for various chemical processes. The fatty acid profile of the oils can be enriched in midchain profiles or the oil can be enriched in triglycerides having specific saturation or unsaturation contents.

Growth of oleaginous microbes and extraction of microbial oil [0125] Oleaginous microbes may be cultivated in a bioreactor or fermenter. For example, heterotrophic oleaginous microbes can be cultivated on a sugar-containing nutrient broth. [0126] Oleaginous microbes produce microbial oil, which comprises triacylglycerides or triacylglycerols and may be stored in storage bodies of the cell. A raw oil may be obtained from microbes by disrupting the cells and isolating the oil. W02008/151149,

W02010/06032, WO2011/150410, WO2012/061647, and W02012/106560 each discloses heterotrophic cultivation and oil isolation techniques. For example, microbial oil may be obtained by providing or cultivating, drying and pressing the cells. Microbial oils produced may be refined, bleached, and deodorized (RBD) as described in W02010/120939, which is entirely incorporated herein by reference. Microbial oils can be obtained without further enrichment of one or more fatty acids or triglycerides with respect to other fatty acids or triglycerides in the raw oil composition.

Microbial Oil Content

[0127] A microbial oil may be characterized by its triacylglycerol (“TAG”) profile. A TAG profile indicates relative amounts of various TAGs, and consequently fatty acids (each TAG molecule is a tri-ester of glycerol and three fatty acids), present in microbial oil. As disclosed herein, fatty acids from microbial oils having TAG profiles comprising high levels of unsaturated fatty acids and/or having low TAG diversity may be hydroformylated and hydrogenated to produce hydroformylated polyols.

[0128] A microbial oil may have a TAG profile comprising a high proportion of one or more unsaturated fatty acids relative to other fatty acids in the microbial oil. A microbial oil may have a TAG profile comprising 60% or more of one or more unsaturated fatty acids.

[0129] A microbial oil may have a TAG profile comprising a high proportion of one or more unsaturated fatty acids relative to one or more saturated fatty acids in the microbial oil. A microbial oil may have a TAG profile comprising low TAG diversity, e.g., fewer TAG species than in, for example, an oilseed oil. Microbial oils rich in a TAG or fatty acid may comprise fewer, different TAG species, or lesser amounts of different TAG species.

[0130] Oils derived from microorganisms having TAG profiles with high purity /high homogeneity /low diversity and high unsaturated fatty acid content are particularly advantageous for use in polyurethane production. Highly pure oils improve product yield and reduce the likelihood of contaminants that adversely affect the physical properties of the resulting polyurethane. Highly unsaturated oils allow for increased numbers of primary alcohol groups formed during hydroformylation and hydrogenation, thereby increasing the functionality, reactivity, and crosslinking during subsequent polymerization reactions. The quantity and type of crosslinking can influence the stability, durability, and rigidity of the resulting polymer.

EXAMPLES

[0203] EXAMPLE 1. An example ski with sidewalls composed of polyurethane derived from microbial oil.

[0204] FIG. 1, Panel A illustrates a top view of an example algal polyurethane composite core. The core composite is comprised of alternating layers of algal derived PU and wood, which can vary in configuration and dimension. Configuration and dimensions of the composite can be optimized to confer specific structural and functional properties in the finished product.

[0205] FIG. 1, Panel B illustrates a cross-sectional view of Panel A. In this example, wood and algal PU foam cores are milled to height of 16 mm. Wood strips are 25-30 mm wide, depending upon their precise location, while algal PU foam strips are 15 mm wide. The specific orientation and geometry of wood or algal foam material used can be optimized depending upon the desired performance characteristics one is trying to achieve.

[0206] Example dimensions are shown in centimeters (cm). The example composite includes seven laminated layers: two layers of algal polyurethane (a), followed by a layer of wood (b), followed by a polyurethane core (a’), a second layer of wood, and two additional layers of polyurethane. Each of the layers are affixed together lengthwise.

[0207] EXAMPLE 2. A quick cure cast urethane formulation.

[0208] A cast urethane formulation comprised of a B-side (polyol) chemistry including 53% wt/wt algal oil polyol (epoxidized algal oil polyol, EAOP), 5% wt/wt 1,4-butanediol, 1.25% wt/wt zeolites, and 0.8% wt/wt catalyst (DABCO; triethylene diamine). Each of the amounts of the 1,4-butanediol, zeolites, and catalyst used was relative to the polyol components in the B-side chemistry. The A-side chemistry comprised of the isocyanate (polymeric MDI).

[0209] Although DABCO catalyst (triethylene diamine) was used herein, other suitable primary or secondary amine catalysts, such as 2,2’-oxybis(N,N-dimethylethylamine), organotin, organozinc, or organozirconium catalysts can be used.

[0210] Although polymeric MDI was used herein, other suitable isocyanates, including pure, monomeric MDI, such as Rubinate ^® 44 and Rubinate ^® 9225, for example. [0211] The zeolites were either UOP L paste or powder containing potassium calcium sodium aluminosilicates of zeolite A type (ca. 3 A pore size). If powder was used, the powder was mixed with the EAOP at a ratio of 1 : 1 wt/wt. The paste was supplied 1 : 1 with castor oil. [0212] The formulation components were mixed vigorously by hand and aliquoted to a handheld dispensing gun equipped with a static mixing tip. The mixture was then cast into a mold having dimensions of 17.3 cm (L) x 17.3 cm (W) x 1 cm (D) and allowed to cure at room temperature (about 23 °C).

[0213] After one hour, the cast was removed from the mold. Using a computer numerical control (CNC) router, 5 dog bone shaped coupons (186 mm long, 23 mm grip length, 128 mm gage length, 8 mm wide, 8.2 mm thick) were prepared for tensile testing according to ASTM D638.

[0214] The coupons were also machined to bars having the dimensions of 8.2 mm wide x 8.0 mm thick x 140 mm long for three-point bend testing. The test was carried out at a span of 110 mm with a cross head rate of 22.4 mm/min.

[0215] The machined coupons were designated as quick cure (QC) cast urethanes and either tested at ambient temperature (23 °C), or by pre-chilling overnight at -20 °C and placing in a plastic bag on ice prior to low temperature (LT) testing (0-2 °C as assessed by IR gun).

[0216] FIG. 2, Panel A shows the results (stress strain curves) of tensile strength testing of QC cast urethanes according to ASTM D638 at room temperature (RT), while FIG. 2, Panel B shows the results at 0-2 °C (LT).

[0217] FIG. 3, Panel A shows the results of three-point bend testing of QC cast urethanes at RT. FIG. 3, Panel B shows the corresponding results at 0-2 °C (LT).

[0218] Coupons used for three-point bend testing were also subjected to durometer testing to assess the hardness of the materials. Results of these tests are shown in TABLE 2.

TABLE 2

[0219] EXAMPLE 3. A slow cure cast urethane formulation.

[0220] A second cast urethane formulation was prepared as described in Example 2 except that the catalyst loading was 0.1% (wt/wt) relative to the polyol components. The formulation components were mixed vigorously by hand and aliquoted to a handheld dispensing gun equipped with a static mixing tip. The mixture was then cast into a mold having dimensions of 17.3 cm (L) x 17.3 cm (W) x 1 cm (D) and allowed to cure at room temperature (about 23 °C).

[0221] After 24 hours, the cast was removed from the mold. Using a CNC router, 5 dog bone shaped coupons (186 mm long, 23 mm grip length, 128 mm gage length, 8 mm wide, 8.2 mm thick) were prepared for tensile testing according to ASTM D638.

[0222] The coupons were also machined to bars having dimensions of 8.2 mm wide x 8.0 mm thick x 140 mm long for three-point bend testing. The test was carried out at a span of 110 mm with a cross head rate of 22.4 mm/min.

[0223] The machined coupons as above, were designated as slow cure (SC) cast urethanes and either tested at ambient temperature (23 °C) or by pre-chilling overnight at -20 °C, and placing in a plastic bag on ice prior to LT testing (0-2 °C as assessed by IR gun).

[0224] FIG. 4, Panel A shows the results (stress strain curves) of tensile strength testing of SC cast urethanes according to ASTM D638 at RT, while FIG. 4, Panel B shows the results at 0-2 °C (LT).

[0225] FIG. 5, Panel A shows the results of three-point bend testing of SC cast urethanes at RT. FIG. 5, Panel B shows the corresponding results at 0-2 °C (LT).

[0226] Coupons used for three-point bend testing were also subjected to durometer testing to assess the hardness of the materials. Results of these tests are shown in TABLE 3.

TABLE 3

[0227] The algal polyol based cast urethanes described here, whether produced by quick cure or slow cure, showed improved physical properties at lower temperatures, both in terms of tensile strength as well as three-point bend testing. Furthermore, the slow cure formulation showed enhanced physical properties relative to the quick cure formulation at both RT and LT conditions. These improved performance characteristics at lower temperatures are relevant to end use applications in winter sports equipment. [0228] EXAMPLE 4. A two component liquid casting resin kit.

[0229] A liquid casting resin kit comprising a resin component (containing isocyanate; A- side chemistry) and a hardener component (polyol; B-side chemistry) was prepared according the formulations described in Examples 2 and 3. The kit was used to prepare two cast PUs using two different curing regimens, and properties of the resulting cast PUs were evaluated. The resin and hardener components are in a percentage by weight (pbw) of 62: 100 and a percentage by volume (pbv) of 1 :2. TABLE 4 shows the processing properties of the cast urethane components. Processing and material temperatures were between about 65-80 °F (about 18-27 °C). Prior to use, the material was stored in tightly sealed containers between 65-90 °F (about 18-32 °C), and kept away from moisture or high humidity.

TABLE 4

[0230] Each of the hardener and resin components was agitated well before combining together (compounding). After compounding, the components were together mixed well before curing. The mold or substrate in which the compounded resin/hardener is poured was also checked to ensure that the mold or substrate was free of dirt, oil, and grease. In some cases, mold release agents were used.

[0231] The appearance, biobased carbon content, hardness, gel time, and demold time for quick and slow cure formulations are shown in TABLE 5. Molded samples prepared from these formulations were allowed to gel and subsequently demolded according to the times and at the temperature indicated in TABLE 5. Samples were subsequently heated for 30 minutes at 75 °C, as opposed to longer cure times at room temperature or accelerated curing at higher temperatures, to mimic potential heat and time profiles in a manufacturing setting. The mechanical properties of the resultant products were measured at 2 °C (low temperature) and at 25 °C (room temperature). These data are shown in TABLE 5. TABLE 5

[0232] Both resins showed excellent physical properties, contained high biobased content as determined by ASTM 6866, and were essentially free of mercury, tin, MOCA (4,4'- methylenebis(2-chloroaniline), and TDI. While the resulting resins were tan in color, the resins were suitable for pigmentation. While the finish on the casted materials depends on the mold or substrate being used, the top surface on open-faced molds had a glossy finish, while a machined material had a huffy appearance. The finish of the casted material was improved by wiping with steel wool/acetone and/or silicone polish.

[0233] For both low temperature and room temperature testing, the slow cure formulation exhibited greater tensile strength, elongation at break, and flexural strength as compared to the quick cure formulation. Further, the performance of materials was better at low temperature, e.g., strength was greater at low temperature than at room temperature. [0234] EXAMPLE 5. A modified cast urethane formulation.

[0235] A cast urethane formulation comprised of components listed in TABLE 6 was prepared as follows. The algal polyol was prepared from an epoxidized ethanol ring opened high oleic algal oil (>88% C18:l, OH# 149, EW 376). All components listed in TABLE 6, except isocyanate (Rubinate ^® M), including algal polyol, zeolites, 1,4-butanediol (1,4-BDO), and DBTDL, were charged in a cup in a dual centrifugal mixer and mixed for 40 sec at 3600 rpm. Subsequently, isocyanate was added and mixed for 20 sec at 3600 rpm. The resulting mixture was then poured in a stainless steel mold (10 cm x 10 cm x 0.2 cm). Samples were left in the mold at room temperature for 48 hours. Thereafter, the samples were demolded and cut in half. Half of the sample was post-cured in an oven at 110 °C for 15 hr, while the other half remained at room temperature.

TABLE 6

[0236] Three coupons, approximately 50 mm (long) x 2.0 mm (thick) x 3.3 mm (wide), were prepared from each formulation and subjected to tensile testing (test speed 50 mm/min at room temperature), as well as Shore hardness and determination of T _g via DSC (3-cycle run, first two cycles: heating to 150 °C and cooling to -90 °C at a ramp of 20 °C/min, the third cycle: heating to 120 °C at 10 °C/min). The testing results for the room temperature (R.T.) and heat cured samples (heat) are shown in TABLE 7.

[0237] These data demonstrate that increasing levels of zeolites and diol (i.e., 1,4-BDO) improved physical properties. In addition, a longer heat cure regime resulted in materials with increased T _g and tensile strength, and a significant decrease in elongation at break. TABLE 7
