Abstract

The invention relates to a copolymerizable emulsifier comprising (meth)acrylic acid esters, selected from compounds of the general formula (1) and (II), where: A is an acrylic group having 3 to 40 carbon atoms, x and y independently of each other are a hydrogen group or a methyl group, B is hydrogen or a sulfate or phosphate group, and n a number in the range of 0 to 40. The invention further relates to methods of using said copolymerizable emulsifier in the emulsion polymerization of olefinically unsaturated monomers to prepare polymers.
