SYNTHESIS AND CHARACTERIZATION OF CROSS-LINKED TRI-POLYMERS OF POLY ACRYLIC ACID AS WATER THICKENING AGENTS

Abstract

A cross-linked poly acrylic acid tri-polymer is successfully synthesized by batch charging polymerization of poly allyl tris buffer, di-vinyl benzene and acrylic acid and this new method is profitable in terms of reducing the toxicity, faster, purity and cheaper than available methods. The morphological structure of the synthesized polymer is studied by SEM and the characteristic functional groups of the synthesized polymers are identified using FTIR. TGA and DSC techniques were employed to study their thermal characterization.
