Cas No.: 26677 -99-6 
Structural Formula:

Other name: ACRYLIC ACID MALEIC ANHYDRIDE COPOLYMER；Copolymer of Maleic and Acrylic Acid; MA-AA; 

1.Performance and usage
 MA/AA is a low molecular weight polyelectrolyte, which is produced by copolymerizing maleic acid and acrylic acid in a certain proportion. It has a strong dispersing effect on carbonates, etc., has high thermal stability, and can be used in harsh conditions such as 300°C. It has good compatibility and synergistic effects with other water treatment chemicals.
It has a good inhibitory effect on the formation of scale including phosphate. Due to its excellent scale inhibition and high temperature resistance, it is widely used in low-pressure boilers, central heating, central air conditioning and various circulating cooling water systems. It can also be used as a chelating dispersant in the textile printing and dyeing industry.
