CA 2311506

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.

L'invention concerne un procédé pour produire des polymères hydrosolubles ou pouvant gonfler dans l'eau, à partir d'acide acrylique ou de dérivés d'acide acrylique, lesdits polymères présentant une faible teneur en monomères résiduels. Ce procédé est caractérisé par l'addition d'un composé d'azote à la solution monomère à polymériser et par le réchauffement ultérieur du polymère à des températures comprises entre 120 et 240 ·C. Les polymères obtenus selon ce procédé s'utilisent entre autres comme floculants, dispersants et absorbants.
