DESCRIPTION General 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. Application Applications of PAA may include: - to study solute diffusion in Polyvinyl alcohol/PAA copolymer hydrogel[1] - synthesizing poly(N-isopropylacrylamide)-block-PAA copolymer which responds to both temperature and pH stimuli[2] - in preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drugs[3] - as thickening agent for adhesives. |
