Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

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.Applications of PAA may include:to study solute diffusion in Polyvinyl alcohol/PAA copolymer hydrogelsynthesizing poly(N-isopropylacrylamide)-block-PAA copolymer which responds to both temperature and pH stimuliin preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drugs as thickening agent for adhesives.
