Abstract

In this research, we synthesized a novel graft copolymer of gelatin-based via radical polymerization mixtures Acrylic acid (AcA) and Acrylamide (AAm) onto gelatin backbones. The polymerization reaction was carried out in an aqueous medium and in the presence of ammonium persulfate (APS) as an initiator. Evidence of grafting was obtained by comparing FTIR and TGA analysis of CMC and the graft copolymer as well as solubility characteristics of the products. The effect of grafting variables, i.e. concentration of AAm, AcA, APS and Gelatin, and temperature was systematically optimized to achieve a highest percent grafting possible. The overall activation energy for the grafting was also estimated to be 23.30kJ/mole.
