Description Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106oC. At temperatures above 200, up to 250oC, it loses water and becomes an insoluble crosslinked polymer anhydride. Solubility of dried PAA in water increases with rise in temperature. Concentrated solutions of PAA in water are thixotropic in nature.
Application PAA is used in the preparation of nano-hydroxyapatite polyacrylic acid (Hap/PAAc) biocomposites.†Other probable s of PAA are: to study solute diffusion in Polyvinyl alcohol/PAA copolymer hydrogels†, 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†, and as a thickening agent for adhesives.
Features And Benefits They can interact with or be dissolved by water or other polar substances.
