Method for producing synthetic 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 process for producing water-soluble or water-swellable polymer products with low levels of residual monomers using acrylic acid and/or acrylic acid derivatives, which process is characterized by adding a nitrogen compound to the monomer solution to be polymerized and subsequent heating of the polymer product at temperatures of from 120 to 240° C. The polymers produced accordingly are suitable for use as flocculants, dispersants and absorbents.
