IN SITU GRAFT COPOLYMERIZATION OF STARCH WITH D,L-LACTIDE IN THE PRESENCE OF POLY(ETHYLENE GLYCOL)

DAI Wen-qi, TU Ke-hua, WANG Li-qun (Dept. of Polymer Science and Engineering, Zhejiang University, Hangzhou 310027, China)  
The in situ graft copolymerization of starch with D,L-lactide was investigated. It is found that lactide can be grafted onto starch via ring-opening polymerization in the presence of poly(ethylene glycol) (PEG), resulting starch-PLA graft copolymers. Increasing the amount of PEG to the reacting system results in the increase of the grafting of PLA onto starch, and the molecular weight of PEG plays a prominent role in affecting PLA grafting.
