EMULSION POLYMERS, AQUEOUS DISPERSIONS AND PROCESSES FOR PREPARING THEM

摘要

The invention relates to an emulsion polymer comprising at least one (meth)acrylate segment that comprises between 1 and 30 % by weight of units derived from (meth)acrylates with at least one double bond and between 8 and 40 carbon atoms in the alkyl group, between 1 and 10 % by weight of units derived from monomers containing acid groups and between 50 and 98.9 % by weight of units derived from (meth)acrylates with between 1 and 6 carbon atoms in the alkyl group, each weight percentage relating to the weight of the (meth)acrylate segment. According to the invention, the emulsion polymer has a particle radius of at least 50 nm.
