Copolymer of Maleic and Acylic Acid (MA/AA)
CAS No.: 26677-99-6
Structural Formula:

Product performance:
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 for phosphate, and has good thermal stability, can be used under high temperature (300℃). MA/AA has good compatibility when used together with other water treatment chemicals. It also has good scale inhibition against phosphonate.
