Abstract

Pronalazak se odnosi na postupak za proizvodnju polimerizata, koji su rastvorljivi u vodi ili bubre u vodi, od akrilne kiseline ili derivata akrilne kiseline, koji se karakterišu vrlo malim sadržajem ostatka monomera, i dodatkom jednog jedinjenja azota rastvoru monomera za polimerizaciju i naknadnim zagrevanjem polimerizata na temperaturu od 120В° do 240В°C. Tako proizvedeni polimerizati pogodni su, izmedju ostalog, za upotrebu kao sredstva za koagulaciju, dispergovanje i apsorpciju.[The invention relates to a method for producing water-soluble or water-swellable polymerizates with a low residual monomer content from acrylic acid and/or acrylic acid derivatives. The method is characterised by the addition of a nitrogen compound to the monomer solution to be polymerised and in that the polymerizate is subsequently heated at temperatures of 120 to 240 В°C. The polymerizates produced according to the inventive method are suitable for use as e.g. flocculants, dispersants and absorbers.
