GLYCIDYL ESTERS OF ALPHA, ALPHA BRANCHED ACIDS COMPOSITIONS

The present invention relates to a composition of a, a- branched alkane carboxylic acids glycidyl esters with a defined isomeric composition; which can lead for example to improved hardness of the coatings derived thereof.

More in particular the invention relates to the compositions of aliphatic tertiary saturated carboxylic acids or α, α-branched alkane carboxylic acids, which contain 9 or 13 carbon atoms and which provide glycidyl esters with a branching level of the alkyl groups depending on the olefin feedstock used and/or the oligomerisation process thereof, and which is defined as below.

It is generally known from e.g. US 2,831,877, US 2,876,241, US 3,053,869, US 2,967,873 and US 3,061,621 that mixtures of , α-branched alkane carboxylic acids can be produced, starting from mono-olefins , such as butenes and isomers such as isobutene, carbon monoxide and water, in the presence of a strong acid.

The glycidyl esters can be obtained according to PCT/EP2010/003334 or the US6433217.

We have discovered that well chosen blend of isomers of the glycidyl ester of, for example, neononanoic acids give different and unexpected performance in combination with some particular polymers such as polyester polyols. The isomers are described in Table 1 and illustrated in Figure 1.

We have found that the performance of the glycidyl ester compositions derived from the branched acid is depending on the branching level of the alkyl groups R ¹ , R ² and R ³ , for example the neononanoic acid has 3, 4 or 5 methyl groups. Highly branched isomers are defined as isomers of neo-acids having at least 5 methyl groups.

The above glycidyl esters compositions can be used for example, is as reactive diluent or as momomer in binder compositions for paints or adhesives.

The glycidyl esters compositions can be used as reactive diluent for epoxy based formulations such as examplified in the technical brochure of Hexion (Product Bulletin: Cardura N10 The Unique Reactive Diluent) .

Other uses of the glycidyl ester are the combinations with polyester polyols, or acrylic polyols, or polyether polyols. The combination with polyester polyols such as the one used in the car industry coating leads to a fast drying coating system with attractive coating properties.

Methods used

The isomer distribution of neo-acid can be determined using gas chromatography, using a flame ionization detector (FID). 0.5 ml sample is diluted in analytical grade dichloromethane and n-octanol may be used as internal standard. The conditions presented below result in the approximate retention times given in table 1. In that case n-octanol has a retention time of approximately 8.21 minute . The GC method has the following settings:

The molecular weights of the resins are measured with gel permeation chromatography (Perkin Elmer/ Water) in THF solution using polystyrene standards. Viscosity of the resins are measured with Brookfield viscometer (LVDV-I) at indicated temperature. Solids content are calculated with a function (Ww- Wd) / Ww x 100%. Here Ww is the weight of a wet sample, Wd is the weight of the sample after dried in an oven at a temperature 110 °C for 1 hour.

Tg (glass transition temperature) has been determined either with a DSC 7 from Perkin Elmer or with an apparatus from TA Instruments Thermal Analysis. Scan rates were respectively 20 and 10°C/min. Only data obtained in the same experimental conditions have been compared. If not, the temperature difference occurring from the different scanning rate has been proved not significant for the results compared.

Methods for the Characterization of the Clear Coats

Pot-life

Pot-life is determined by observing the elapsed time for doubling of the initial viscosity at room temperature, usually 24.0 ± 0.5 °C. The initial viscosity of the clear coat is defined at 44-46 mPa.s for Part 1 and 93-108 mPa . s for Part 3 measured with Brookfield viscometer.

Application of clearcoat

Q-panels are used as substrates. Then the panels are cleaned by a fast evaporating solvent methyl ethyl ketone or acetone. For Part 1 the clearcoat is spray-applied on Q-panels covered with basecoat; for Parts 2 & 3 the clearcoat is barcoated directly on Q-panels. Dust free time

The dust free time (DFT) of clear coat is evaluated by vertically dropping a cotton wool ball on a flat substrate from a defined distance. When the cotton ball contacts with the substrate, the substrate is immediately turned over. The dust free time is defined as the time interval at which the cotton wool ball no longer adhered to the substrate.

Hardness development

Hardness development is followed using pendulum hardness tester with Koenig method.

Blocking isomers

Whereas the carbon atom in alpha position of the carboxylic acid is always a tertiary carbon atom, the carbon atom(s) in β position can either be primary, secondary or tertiary.

Neononanoic acids (V9) with a secondary or a tertiary carbon atoms in the β position are defined as blocking isomers

Formulation of the Clear Coats

A clear coat is formulated with one of the polyester based acrylic polyol (from examples 11, 12 or 13, the curing agent (HDI, Desmodur N3390), the thinner, the levelling agent (BYK- 331) and the catalyst (dibutyltin dilaurate, DBTDL) according to the amounts indicated in table 11.

Table 11: Clear coats, formulations

Characterization of the Clear Coats

The clearcoat formulations (from table 11) are barcoat applied on degreased Q-panel. The panels are dried at room temperature, optionally with a preliminary stoving at 60 °C for 30 min. Clear coats have been characterized among others by measuring the dust free time and Koenig hardness development (see table 12) .

Table 12: Clear coats, drying (curing) properties Observation (see table 12) : significant improvement (lower dust free time and quicker hardness development) is observed when replacing Cardura E10P by GE9H for the polyester cooking. Improvement is even more significant when Cardura E10P is complementary replaced by GE9H for the acrylic polyol cooking. Example 14 Comparative

Table 21: Clear coats, formulations Characterization of the Clear Coats

The clearcoat formulations (from table 21) are barcoat applied on degreased Q-panel, optionally on basecoated Q-panel.
