METHOD FOR PRODUCING SYNTHETIC POLYMERIZATES WITH VERY LOW RESIDUAL MONOMMER CONTENT, THE PRODUCTS PRODUCED ACCORDING TO THIS METHOD AND THE USE THEREOF

摘要

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 °C. The polymerizates produced according to the inventive method are suitable for use as e.g. flocculants, dispersants and absorbers.
