Abstract

The present invention relates to the use of a polymer from the polymerization of 2-octyl acrylate of renewable origin and optionally at least one other monomer, as a binding agent in or for the production of a coating composition.

First claim

The invention claimed is:

1. A binding agent for aqueous coating compositions, said binding agent comprising a polymer resulting from the polymerization of 2-octyl acrylate of renewable origin and optionally at least one other monomer, wherein the polymer has a glass transition temperature (Tg), calculated by Fox's law, of between −40° C. and +40° C., and is in aqueous dispersion form.

2. The binding agent of claim 1 wherein said other monomer is selected from the group consisting of: vinylaromatic monomers; ethylenically unsaturated nitriles; esters of ethylenically unsaturated mono- and dicarboxylic acids; esters of monocarboxylic acid and vinyl and allyl alcohol; ethylenically unsaturated mono- and dicarboxylic and sulfonic acids; amides of ethylenically unsaturated mono- and dicarboxylic acids; N-vinyllactams; N-vinylamides; N,N-diallylamines; N,N-diallyl-N-alkylamines; allyl- and vinyl-substituted nitrogenous heterocycles; and their mixtures.

3. The binding agent of claim 2 wherein said other monomer is selected from the group consisting of esters of ethylenically unsaturated mono- and dicarboxylic acids, vinylaromatic monomers, and their mixtures.

4. The binding agent of claim 1 wherein the polymer has a glass transition temperature (Tg), calculated by Fox's law, ranging from −30° C. to +30° C.

5. The binding agent of claim 1 wherein the polymer is a copolymer including from 30% to 75% by weight 2-octyl acrylate, with respect to the total weight of the copolymer.

6. The binding agent of claim 1 wherein the polymer represents, by dry weight, from 5% to 50% by weight, with respect to the total weight of the composition.

7. A paint, mortar, coating, varnish or ink composition comprising the binding agent of claim 1 .
