METHOD FOR PRODUCING WATER-SOLUBLE OR WATER-SWELLABLE POLYMERIZATES WITH A VERY LOW RESIDUAL MONOMER CONTENT, PRODUCTS PRODUCED ACCORDING TO THIS METHOD AND THE USE THEREOF

摘要

The invention relates to a method for producing water-soluble or waterswellable 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 ~C. The polymerizates produced according to the inventive method are suitable for use as e.g. flocculants, dispersants and absorbers.
