Poly(acrylic acid)

• Catalog Number: ACM9003014-26
• Product Name: Poly(acrylic acid)
• CAS: 9003-01-4
• Category: Inhibitors
• Description: Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106oC. At temperatures above 200 to 250oC, it loses water and becomes an insoluble crosslinked polymer anhydride. Solubility of dried PAA in water increases with rise in temperatures. Concentrated solutions of PAA in water is thixotropic in nature.
