Itaconate ester copolymers as scale inhibitors

摘要

Copolymers of an acrylic acid and a lower alkyl ester of itaconic acid are added to an aqueous medium as scale inhibitors and as dispersants of particulate matter. In a preferred embodiment, the copolymers are composed of 70 to 95 weight parts of an acrylic acid and 5 to 30 weight parts of a lower alkyl ester of itaconic acid and the copolymers are added to the aqueous medium amount of about 1 to 200 ppm.
