Fund Project: This study was supported by the National 863 Program of China (No. 2003AX32X210).

The novel biodegradable copolymer PDLLA-(MAH-Diol)_n-PDLLA with unsaturated bond was synthesized by copolymerizing lactide and prepolymer, which was prepared by the polycondensation of maleic anhydride and poly (ethylene glycol), using p-toluene sulphonic acid as catalyst. The new copolymer has improved hydrophilicity and flexibility. The structure and properties of the novel polymers were studied by FTIR, NMR, GPC-MALLS and DSC.
