Synthesis and Characterization of Starch/Lactic Acid Graft Copolymer Catalyzed by Zinc Oxide
Abstract:
Starch/lactic acid graft copolymer was prepared with in-stiu graft copolymerization catalyzed by zinc oxide.The graft copolymer was characterized by FT-IR,1H NMR,XRD and SEM.Effects of the reaction temperature,mass ratio between corn starch and lactic acid,amount of the catalyst and the reaction time on the grafting degree were studied.It was found that the highest grafting degree could reach 14.20% with the mass ratio of corn starch to lactic acid being 5:1,and the mass fraction of the catalyst being 1.0% of the lactic acid,and the reaction was carried out at 95℃ for 11 h.
