Abstract

Polymers I suitable as dispersing resins are obtained by reacting A. a polymer II obtained by reacting at least one compound III selected from the group consisting of PA1 a) an ester IV of PA2 a1) an .alpha.,.beta.-unsaturated carboxylic acid V and PA2 a2) an alkyl alcohol VI of 1 to 25 carbon atoms, PA1 b) an ester VII of PA2 b1) vinyl alcohol and PA2 b2) a saturated carboxylic acid VIII of 1 to 4 carbon atoms, PA1 c) vinyl chloride PA1 d) styrene or vinyl benzenes which carry an alkyl group of 1 to 4 carbon atoms on the benzene ring, in the presence of a compound IX which contains an N-oxyl radical function, with B. at least one compound X comprising PA1 a) 50 to 100% by weight, based on X, of at least one compound XI selected from the group consisting of PA2 a1) an ester XII of PA3 a) an .alpha.,.beta.-unsaturated carboxylic acid XIII and PA3 b) an alkyl alcohol XIV of 2 to 10 carbon atoms which carries at least one polar or acidic group, PA2 a2) an amide XV of PA3 a) an .alpha.,.beta.-unsaturated carboxylic acid XVI and PA3 b) ammonia or an amine XVII of 2 to 10 carbon atoms which carries at least one polar or acidic group, PA2 a3) N-vinyl compounds XVIII, PA2 a4) styrene sulfo…
