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 s of PAA may include:
to study solute diffusion in Polyvinyl alcohol/PAA copolymer hydrogel
synthesizing poly(N-isopropylacrylamide)-block-PAA copolymer which responds to both temperature and pH stimuli
in preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drugs
as thickening agent for adhesives.
Features And Benefits They can interact with or be dissolved by water or other polar substances.
