摘要：

Chitosan grafted oligo(L-lactic acid) copolymers with different length of side chain were prepared through the reaction of terminal aldehyde group of oligo (ir-lactic acid) (OLLA) and amino groups of chitosan. The mean molecular <LF>mass of the grafting OLLA chain was ca. 600 similar to 5 000. The graft copolymers are soluble in DMSO. DMF and acetic acid. The synthesis method and structure described here provide chitosan-g OLLA copolymers with broad applicability.
