Application

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.

Properties:

PAA is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. PAA can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAA is used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

Usage:

PAA can be used as scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems. Dosage should be in accordance with water quality and equipment materials. When used alone, 1-15mg/L is preferred.

Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106^oC. At temperatures above 200, up to 250^oC, 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.
