Abstract

See full text

A finely divided, cationic, aqueous polymer dispersion, obtained by (I) solution polymerizing a first mixture containing (a) 15-40% by weight of a mixture of (a1) a (meth)acrylate and (a2) a (meth)acrylamide, (b) 40-85% by weight of styrene, (c) 0.5-5% by weight of an ethylenically unsaturated monomer, and (d) 0-20% by weight of a nonionic, ethylenically unsaturated monomer differing from (b); (II) adding water; and (III) emulsion polymerizing a second monomer mixture containing (i) 0-29% by weight of styrene, (ii) 50-100% by weight of a C1- to C18-(meth)acrylate, (iii) 0-30% by weight of a vinyl ester of a C1-C30-carboxylic acid, and (iv) 0-30% by weight of a nonionic ethylenically unsaturated monomer differing from (i), (ii), and (iii), wherein at least one of the solution and emulsion polymerizing are performed in the presence of 0-10% by weight of a regulator.
