Abstract

A new class of technologically advanced material like superabsorbent polymers involved multidisciplinary research started when its potential is recognized. Rice straw-graft-polyacrylamide (RS-g-PAM) superabsorbent polymers was synthesized via simultaneous cross linking and graft copolymerization of acrylamide monomer onto backbone of rice straw using complex initiating system [CuSO4/glycine/ammonium persulfate] in an aqueous medium without and with N,N-methylenebisacrylamide as crosslinker. The chemically modified rice straw, RS-g-PAM have been characterized by FT-IR and their morphology was studied by scanning electron microscopy. Systematically, variables that affect the water absorbance behaviours of RS-g-PAM SAPs were optimized with the effects of solvent, degree of neutralization and crosslinker concentrations. The tensile and dyeing properties of RS-g-PAM superabsorbent polymers were also studied. A mechanistic pathway in synthesizing RS-g-PAM SAPs was suggested. The biodegradation and water absorbency have been carried out for its ecofriendly nature and better commercialization.
