Investigation effective parameters onto γ-radiation Graft Polymerization Acrylamide onto Carboxymethylcellulose

摘要

The monomer, acrylamide, was graft copolymerized onto Carboxymethylcellulose (CMC) using γ-rays asinitiator. The reactions were carried out in a homogenous aqueous medium. The results showed that the thermalstability of grafted polyacrylamide samples was remarkably improved. A plausible mechanism of grafting hasalso been suggested. The effect of various factors affecting on grafting, i.e. dose of δ-rays and concentration ofthe monomer and polysaccharide as well as the reaction temperature were studied by conventional methods toachieve the optimum grafting parameters.
