PENDANT ACIDIC PHOSPHONIC ESTER GROUP-CONTAINING COPOLYMERS OF OLEFINICALLY UNSATURATED MONOMERS, PROCESS FOR THEIR PREPARATION AND USE THEREOF

摘要

Pendant acidic phosphonic ester group-containing copolymers of olefinically unsaturated monomers, preparable by free-radically polymerizing (A) at least one free-radically polymerizable acidic phosphonic ester preparable by reacting (A1) at least one phosphonic acid of the general formula R-P(=O) (-OH)2 in which R is at least one substituted or unsubstituted organic radical which contains a free-radically polymerizable carbon-carbon double bond and contains heteroatoms or is free thereof, with (A2) at least one epoxy group-containing compound essentially or entirely free of free-radically polymerizable groups, in an equivalents ratio of acid groups (P-OH) to epoxy group = 2:1 to 1.2:1; with (B) at least one free-radically polymerizable monomer other than (A); process for their preparation and use thereof.
