Abstract

The monomer, acrylonitrile, was graft copolymerized onto Chitosan using γ-rays as initiator. The reactions were carried out in a homogenous aqueous medium. After removal of the homopolymer, the graft copolymer was characterized by FTIR ,TGA and DTG spectroscopies. The thermal properties of crude Chitosan and grafted with monomer were also evaluated with a simultaneous thermal analysis system. The synthetic conditions were systematically optimized through studying the influential factors including temperature, concentration of the initiator, acrylonitrile monomer and Chitosan. The graft copolymerization reactions were kinetically investigated using semi-empirical expressions and a suitable rate expression has been derived.
