New reticules be used as 0001 carboxylic copolymers in aqueous medium and their preparation

摘要

The invention relates to the chemistry of the polymers. / p & & p & it relates to the carboxylic copolymers reticules obtained by copolymerizing a carboxylic monomer unsaturated, a crosslinking agent, an ester of acrylic acid or methacrylic acid with a polyalkylene glycol, and, optionally, an alkyl acrylate or methacrylate. / p & & p & use as 0001, in particular of media containing dissolved salts.
