Copolymer of Maleic and Acylic Acid ( MA/ AA)

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.
