| 摘 要： | The novel biodegradable copolymer PDLLA-(MAH-Diol)_n-PDLLAwith 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 fexibility. The structure and properties of the novel polymers were studied by FTIR, NMR, GPC-MALLS and DSC.
