Chitosan grafted oligo( L ‐lactic acid) copolymers with different length of side chain were prepared through the reaction of terminal aldehyde group of oligo( L ‐lactic acid) (OLLA) and amino groups of chitosan. The mean molecular mass of the grafting OLLA chain was ca. 600 ∼ 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.Structure of chitosan‐ g ‐oligo( L ‐lactic acid).
