Synonyms: AA/MA, Belclene 283, Poly(acrylic acid-co-maleic acid) Solution

Structural Formula:

Properties:

MA/AA is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic

acid. It shows good dispersant performance against carbonate and scale inhibition for

phosphate. It has good thermal stability, can be used under high temperature (300℃).

MA/AA has good compatibility when used together with other agents. It is widely used in low-

pressure boiler, centralized heating, centralized air-conditioner and circulating cool system. It

can also be used as chelating dispersants in woven and dyeing fields.
