Abstract

The preparation of terpolymers by free radical polymerization of an unsaturated dicarboxylic acid with an unsaturated monocarxylic acid and a further saturated monomer which contains no free carboxyl groups, in an aqueous medium, is carried out, according to the invention, in the presence of surfactant compounds.
