Abstract

This invention deals with novel copolymers having K values from 5 to 80 prepared by the radical polymerization of: PA1 (A) 20 to 80 weight percent, based on the total weight of (A) and (B), of at least one olefinic unsaturated polyoxyalkylene alcohol adduct or a polyester alcohol adduct; PA1 (B) 80 to 20 weight percent, based on the total weight of (A) and (B), of at least one vinyl monomer selected from the group consisting of N-vinylformamide, N-vinyl-2-pyrrolidone, N-vinyl-piperidone, N-vinyl-2-caprolactam, N-vinylimidazole, N-vinyl-2-ethylene-urea and N-vinyl-2-propylene-urea; PA1 (C) 0 to 40 parts by weight of glycidyl acrylate and/or glycidyl methacrylate; PA1 (D) 0 to 10 parts by weight of at least one .alpha.,.beta.-monoolefinic unsaturated acid; and PA1 (E) 0 to 30 parts by weight of at least one olefinic unsaturated carboxylic acid amide and or carboxylic acid ester and/or styrene; whereby the parts by weight of (C), (D) and (E) are each based on 100 parts by weight of monomers (A) and (B). The copolymers are used as auxiliaries and/or additives, for example, as dispersing agents and/or emulsification agents or as additives for improving the mechanical properties in formu…
