| Physical or chemical modification of the starch molecule or granule is a viable alternative to solving some of these problems of starch containing materials. The starch graft copolymer is representative of the modification of the starch molecule by chemical method. Great effort in chemical modification of starch is grafting starch with completely biodegradable polymers, such as Poly(å-caprolactone) and Poly(lactic acid). In this paper, tetrabutyl titanate was used to modify starch to prepare the macromolecular initiator for the polymerization of lactic acid to synthesis the starch grafted PLA copolymer. Different temperature of the reaction and content of catalyst used were studied to obtained ideal modification condition |
