Glacial Acrylic Acid (GAA)
CAS Number: 79-10-7
Empirical Formula: C3H4O2
Glacial Acrylic Acid Monomer (GAA) is an unsaturated carboxylic acid co-monomer used in a wide range of copolymers. GAA readily copolymerizes with acrylic and methacrylic esters, ethylene, vinyl acetate, styrene, butadiene, acrylonitrile, maleic acid esters, vinyl chloride and vinylidene chloride. Copolymers which contain GAA can be solubilized or exhibit improved dispersed in water; the carboxylic acid moiety can be used for coupling or crosslinking reactions. GAA copolymers can be used in the form of their free acids, ammonium salts or alkali salts in applications such as thickeners, dispersing agents, flocculants, protective colloids and polymer dispersions, wetting agents, coatings, adhesives, inks and textile finishes. GAA is also used in a wide variety of specialty copolymers in drilling fluids and mineral processing chemicals, water treatment polymers and superabsorbent materials.
GAA has the chemical structure shown below:
