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 present invention relates to a process for preparing a water-soluble or water-expandable polymer product from acrylic acid and / or acrylic acid derivatives which are partially or completely neutralized with nitrogen compounds and having trace levels of residual monomers, which are then polymers at temperatures of 120 to 240 ° C. It is characterized by heating the product. The polymers thus prepared are suitably used as coagulants, dispersants and absorbents.
