MA/AA Copolymer
Acrylic Acid and Maleic Acid Copolymer
CAS No.: 26677-99-6
Properties:
MA/AA is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. It has good dispersant performance against carbonate, and scale inhibition against phosphate. It has good thermal stability, can be used at high temperature (300℃). MA/AA has good compatibility when used together with other agents. MA/AA is widely used in low-pressure boiler, central heating, centralized air-conditioner and circulating cooling water system. It can also be used as chelating dispersants in textile and dyeing fields.
