Abstract

Oppfinnelsen angår en fremgangsmåte for fremstilling av vannløselige eller vannsvellbare polymerisater med et lavt restmonomerinnhold fra akrylsyre og/eller akrylsyrederivater. Fremgangsmåten er kjennetegnet ved tilsetningen av en nitrogenforbindelse til monomerløsningen som skal polymeriseres og i at polymerisatet deretter oppvarmes ved temperaturer på 120-240°C. Polymerisatene produsert ifølge den oppfinneriske fremgangsmåten er egnet til bruk f.eks. som flokkuleringsmidler, dispergeringsmidler og absorberingsmidler.
