Abstract

Pronalazak se odnosi na proizvodnju u vodi rastvorljivih, odn. u vodi bubrećih polimerizata od delimično ili potpuno neutralisane akrilne kiseline i/ili derivata akrilne kiseline pomoću jedinjenja azota sa vrlo malim sadržajem ostatka monomera, naznačen time, što se polimerizat naknadno zagreva na temperaturu od 120 do 240В°C. Tako proizvedeni polimerizati su pogodni, izmedju ostalog, za upotrebu kao sredstva za koagulaciju, dispergovanje ili apsorpciju.[The invention relates to a method for producing water-soluble or water-swellable polymerizates with a very low residual monomer content using acrylic acid and/or acrylic acid derivatives which have been partially or completely neutralised with nitrogen compounds. The method is characterised in that the polymerizate is subsequently heated to 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.
