Title: Optimal preparation conditions and characterizations of graft copolymerization for VAc onto potato starch
Abstract: This paper mainly studies the influencing factors for the grafting copolymerization of the vinyl acetate onto potato starch.The orthogonal experiment indicates that the optimum reaction condition :initiator density is 18 mmol/L,reaction temperature is 60℃,reaction time is 3.5 h,monomer allocated proportion is 2.5∶1,starch density is 5% and the optimal grating ratio is 99.85%.Finally,the existence of the grafting copolymerization of the vinyl acetate onto potato starch is confirmed by the structure analysis of the starch grafting copolymerization using SEM,XRD and FTIR.
