OXIRANE (ETHYLENE OXIDE) POLYURETHANE COATINGS

BACKGROUND OF THE INVENTION

[0001] Hydrophilic, i.e., water loving coatings (hereafter referred to as "WLC") are a utilitarian chemistry that may be used for hydrophilic and hydrophobic polyurethane epoxies as a replacement of isocyanate-based coatings on, for example, medical devices. WLC chemistry is attractive since prior art isocyanates-based coating compositions and coatings that may be used present possible health concerns. Another concern, with isocyanates, is the isocyanate sensitivity to water which reacts therewith to evolve carbon dioxide. That side reaction produces a very rough coating due to micro roughness when carbon dioxide exits the coating forming small pin holes. However, once the isocyanate is end capped to form polyurethane epoxy (glycidyl carbamate) in accordance with this invention, reactions with water and off gassing are no longer a concern and health concerns are significantly reduced. The use of WLC chemistry, in medical devices, and other coating areas, is thusly very attractive particularly for medical device applications.

SUMMARY OF THE INVENTION

[0002] WLC synthesis reactions can be optimized generally by running at lower temperatures which tends to reduce side reactions. Reaction order is also a very important consideration in WLC development. In the case of oxirane polyurethane-based WLC's the methylenebisdiisocyanate (MDI) should be either a liquid or a melted solid before polyol additions and that adipic acid dihydrazide is fully reacted before adding dibutyltin dilaurate catalyst and glycidol. Adding glycidol too early may result in amine reactions with glycidol, and addition of catalyst too early may alter the chain extending network and form a less desirable coating. WLC glycidyl (oxirane functionality) termination has shown an increase in coating adhesive and cohesive strength.

In the above formulae:

"η ', relating to PEO, falls in the range of about 500 to about 45,000 or higher; "n ₂ ", relating to polyTHF, falls in the range of about 3 to about 600 or higher;

"n ₃ ", relating to PDEGA, falls in the range of about 2 to about 60,000 or higher; and "n ₄ " is lower alkylene, n ₄ falling in the range of 1 to about 4.

Note that the n ₄ alkylene group optionally couples other isocyanate moieties as is noted below. 1. Glycidol, PEO (polyethylene oxide), dimethylol propionic acid (DMPA),

polytetrahydrofuran (polyTHF), and poly [di(ethylene glycol)adipate]

(PDEGA hydroxyl) can react with methylenebisdiisocyanate for chain

extension.

2. Adipic acid dihydrazide (AAD) reacts with isocyanate for chain extension.

3. End group is terminated with glycidol for glycidyl functionality.

4. Reaction kinetics are faster with an aromatic group next to isocyanate.

The monomers and oligomers (including the genericized polymer

constituents) and synthetic route noted about was used to produce

coatings/compositions of this invention.

[0003] Side reaction free reaction scheme to terminate with epoxy end groups and minimize side reactions.

[0004] The terminal oxirane polyurethane chemistry coatings of this invention primary reactions that make up the polyurethane coatings of this invention are listed below:

[0005] 1, Terminal Oxirane Polyurethane Reactive Coating Compositions are an extremely lubricious durable coating that contains both hard and soft segments. This structure contains polyurethane and epoxy groups. This is a modified aqueous and solvent soluble material to increase physical crosslinks via hydrogen bonding. This structure relies on physical crosslinks for strength through hard segment domains. The hard segments contain aromatic groups, which also stack by pi-bond interactions. "Hard segments" as the term is used herein means substantially crystalline.

[0006] 2. Terminal A composition comprising Epoxy urethane ester carboxylic acid alkylene oxide reactive coating compositions

This example describes the preparation of an inventive water-loving coating (WLC) Epoxy urethane ester carboxylic acid alkylene oxide reactive coating compositions. A 500 mL four neck reaction kettle with condenser, nitrogen inlet and model Gemini J-KEM temperature controller, mechanical stirrer, and heating mantel was used for resin synthesis. 16.8 g of methylenebisdiisocyanate (MDI) >99.0% was charged to the reactor. The temperature was held at 40 degree C for 40 minutes for solid softening. Next, 62.5 g of Poly [di(ethylene glycol) adipate] average M _n -2,500, 72.5 g of Poly(tetrahydrofuran) average M _n -2,900, and 3.35 g of 2,2-Bis(hydroxymethyl)propionic acid 98% was added, in the following order and homogenized by stirring for 5 minutes at 40.degree. C. To this homogenized mixture 150 grams of Poly (ethylene oxide) average M _v 100,000, powder was added immediately following the addition of l-Methyl-2-pyrrolidinone anhydrous, 99.5%. The solution homogenized by mixing thoroughly for 40 minutes. Four drops Dibutyltin dilaurate 95%were added drop wise and the reaction mixture was held at 40 degrees C for one hour. After one hour 3.7 grams glycidol were added and the temperature was held overnight until reaction completion.

[0007] 3. Terminal Oxirane Polyurethane Urea chain extender/(no addition of water). Reactive Coating Compositions are an extremely lubricious durable coating that contains both hard and soft segments. The structure contains polyurethane, urea and epoxy groups. This is a modified aqueous and solvent soluble material that employs urea formation to increase physical crosslinks via hydrogen bonding. Carboxylic acid functionality in the polymer backbone and glycidol end groups add crosslinking. The epoxy end groups help with adhesion and cohesive strength. This structure relies on crosslinks much like the polyurethane epoxy but contains a chain extender based off adipic acid dihydrazide.

[0008] 4. Terminal Oxirane Polyurethane Urea chain extender/(water excess).

Reactive Coating Compositions are an extremely lubricious durable coating that contains both hard and soft segments i.e., crystalline and amorphous segments. This structure contains polyurethane, urea and epoxy groups. This is a modified aqueous and solvent soluble material employs urea formation to increase physical crosslinks via hydrogen bonding. Carboxylic acid functionality in the polymer backbone and glycidol end groups add crosslinking, the reaction of isocyanate forms an unstable carbamic acid that forms an amine. The amine quickly reacts with isocyanate functionality to form a urea.

[0009] Water functionality reacts with excess MDI isocyanate to release C0 ₂ and form an amine. The amine functionality reacts with excess isocyanate to form additional urea linkages. The water/amine reaction is highly, physically crosslink the system and enhance its mechanical properties. The active hydrogen of the secondary amine can further react with excess isocyanate to slightly crosslink the system. The combination of urea, and polyurethane hard segments and glycidol functionalities lead to a superior crosslinking system.

Water reactions with isocyanate to form urea [0010] 5. Terminal Oxirane Polyurethane Amide/Amide Urea/(no addition of water). Reactive Coating Compositions are an extremely lubricious durable coating that contains both hard and soft segments. This is structure contains polyurethane, urea, amide (amide to form urea) and epoxy groups. This is a modified aqueous and solvent soluble material employs amide formation that may undergo additional reactions to form urea. Urea and hard segments yield an increase in hydrogen bonding for physical crosslinks, carboxylic acid functionality in the polymer backbone and glycidol end groups add crosslinking. Amide functionality can continue to react with isocyanate to form urea. This crosslinking system helps increase durability of the basecoat.

Isocyanate reaction with amide to form crosslinked urea

[0011] For example, DMPA was used to construct the polymer backbone for the introducing carboxylic acid functionality. This functionality reacts with excess MDI isocyanate around 80C to form an amide bond. The amide reaction is to slightly cross-link the system and increase its mechanical properties. The active hydrogen of the amide functionally can further react with excess isocyanate to form urea. The combination of amide, urea, and polyurethane hard segments and glycidol functionalities lead to a superior crosslinking system.

SUMMARY OF WLC CONNECTIVITY:

[0014] Basecoat terminal epoxy groups react with top coat epoxy groups through ARM amine functionality which increase adhesive strength. Basecoat chemistry contains Easaqua XM-502, which is added during the base coat mixing step. This aqueous isocyanate contains mpeg for use in water based applications. When this material is added to basecoat the isocyanate reacts with the carboxylic acid and open epoxide hydroxyl groups for basecoat cohesive strength. Easaqua XM-502 also reacts with top coat ARM and open hydroxyl groups for adhesive strength.

[0015] Once crosslinked, with Easaqua XM-502, then the base coat becomes a hydrogel. The hydrogel crosslinks take in water and swell via soft segments (Terethane, PEO and PEDGA) to render the coating water loving with high lubricity. Crosslink chemistry allows water to become retained within the walls of the soft segment without going into solution. This chemical and physical process leads to an extremely durable and lubricious coating.
