An amphiphilic block copolymer poly (D,L-lactide-b-ethylene glycol)(PLA-mPEG) was synthesized via copolymerization of monomethoxypoly (ethylene glycol) with lactide prepared by the catalyst-free method.The copolymer PLA-mPEG₇₅₀ shows the characteristic structures of both PLA and mPEG₇₅₀ determined by FT-IR,and its molecular weight was determined by GPC.The surface tension of the aqueous solutions of the amphiphilic copolymer was measured and the critical micelle concentration (CMC) was calculated to be in the range of 3.5×10^-5~5.8×10^-5 mol/L,showing that the surface activity of these di-block copolymers is similar to that of typical surfactants.The copolymer can self-associate in aqueous solution to form micelle,and different micelle could be prepared by changing the conditions.
