Synthesis and characterization of novel swollen cross-linked poly acrylic acid

Abstract

A cross-linked poly acrylic acid super absorbent polymer has been successfully synthesized by reacting poly allyl sucrose, styrene and acrylic acid batch charging in aqueous medium under the occurrence of nitrogen atmosphere. This novel method is profitable in terms of reducing the toxicity and is fast and economical than available methods. The morphological structure of the synthesized polymer was studied by SEM which showed layered selfassembled structures. Using FTIR, the characteristically involved functional groups of the functionalized polymers were identified. To analyze the thermal character of the prepared polymer in terms of their endothermic or exothermic behavior, TGA and DSC techniques were employed. The synthesized materials could be used as water absorbing agents in the field of material science and technology. Keywords: Poly allyl sucrose, styrene, acrylic acid, water absorbing agent, particle size, copolymer composition, TGA, DSC, FT-IR, SEM.
