Abstract

En fremgangsmåte for fremstilling av kopolymerer ved friradikalpolymerisasjon av a) fra 5 til 95 vekt% av en monomer med formelen l R1 R2 (l) R3 b) fra 95 til 5 vekt% av en monomer av formelen II fv° (II) hvor i hver tilfelle R1 og R2 er H eller Ci-Ca-alkyl, R3 er H eller d-Cs-alkyl, og n er fra 1 til 3, og c) fra O til 40 vekt% av en ytterligere monomer som er fullstendig vannløselig eller har begrenset vannløselighet, hvor polymerisasjonen gjennomføres i et vandig medium.A process for preparing copolymers by free radical polymerization of a) from 5 to 95% by weight of a monomer of formula I R1 R2 (l) R3 b) from 95 to 5% by weight of a monomer of formula II fv ° (II) in each case R 1 and R 2 are H or C 1 -C 3 alkyl, R 3 is H or d-C 5 -alkyl, and n is from 1 to 3, and c) from 0 to 40% by weight of a further monomer which is completely water-soluble or has limited water solubility, where the polymerization is carried out in an aqueous medium.
