ABSTRACT:
The invention is related to the synthesis of novel types of maleic-acrylic copolymers containing 60 to 100% of maleate units (by weight), respectively, 40 to 0% of acrylate units (by weight) based on the sum of both monomeric units composing the copolymer. These copolymers show significant techno-economical and ecological advantages over previously synthesized and described acrylic-maleic copolymers. According to the optimal synthetic procedure for this class of copolymers, one uses very concentrated starting alkaline maleate solutions (at best over 60%), hydrogen peroxide and alkaline peroxy salts as initiators--catalysts for the copolymerization process, as well as reaction temperatures between 105.degree. and 115.degree. C. The obtained copolymers have average molecular masses around 20000, while CCDC values are approximately 17-18 ml 0,25M Calcium Acetate per 1 g of copolymer. The obtained copolymers are well suited for their use as incrustation inhibitors, dispersants or ionic exchangers.
