Descrizione generale
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.
Applicazioni
PAA is used in the preparation of nano-hydroxyapatite polyacrylic acid (Hap/PAAc) biocomposites.†Other probable applications 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.
