The Research on Synthetic Method of Starch/Lactic Acid Graft Copolymer Catalyzed with Sulfuric Acid

Article Preview

Abstract:

The starch/lactic acid grafting copolymer has been prepared by one-step reaction of corn starch with lactic acid catalyzed with sulfuric acid, and the structure of product was characterized by IR, XRD, SEM and 1H-NMR. The experimental results showed that sulfuric acid could catalyze the graft copolymerization of starch with lactic acid, and the grafting degree of starch could reach 55.4%.
