Summary:Polyvinyl alcohol-stabilized (meth)acrylic ester polymers, processes for preparing and uses for the same. Where the polyvinyl alcohol-stabilized (meth)acrylic ester polymers have particle sizes Dw of from 100 to 900 nm in the form of aqueous dispersions or water-redispersible powders. Where the (meth)acrylic ester polymers are based on(a) 1% to 30% by weight of one or more vinyl esters of carboxylic acids having 5 to 15 carbon atoms,(b) 20% to 80% by weight of one or more (meth)acrylic esters, wherein the homopolymer of which has a glass transition temperature Tg of ≤20° C.,(c) 10% to 70% by weight of one or more (meth)acrylic esters, wherein the homopolymer of which has a glass transition temperature Tg of ≥50° C., and(d) optionally one or more further ethylenically unsaturated monomers.The percentages by weight are based on the total weight of the (meth)acrylic ester polymers.
