The term MA/AA.Na refers to the Sodium Salt of Maleic Acid/Acrylic Acid Copolymer.
MA/AA.Na CAS Registry Number is 52255-49-9.
This copolymer is widely used in various industrial applications, primarily as:
-
A scale inhibitor and dispersant in water treatment (e.g., cooling water, boiler water, reverse osmosis systems).
-
A superplasticizer in concrete admixtures.
-
A dispersing agent in pigments, ceramics, and detergents.
It’s important to distinguish this from the homopolymers (like poly(acrylic acid) sodium salt, CAS 9003-04-7) and other related copolymers, as the specific monomer ratio and structure in MA/AA.Na give it unique properties.
