| 英文摘要 | Macroinitiator-amino terminated poly(ethylene glycol) (PEG) (NH2-PEO-NH2) was prepared by converting both terminal hydroxyl groups of PEG to more reactive primary amino groups. The synthetic route involved reactions of chloridize, phthalimide and finally hydrazinolysis. Furthermore, poly(gamma-benzyl-L-glutamate)-poly(ethylene oxide)-poly(gamma-benZyl-L-glutamate) (PBLGPEO-PBLG) triblock copolymer was synthesized by polymerization of gamma-benzyl-L-glutamate N-carboxyanhydride (Bz-L-GluNCA) using NH2-PEO-NH2 as macroinitiator. The resultant NH2PEO-NH2 and triblock copolymer were characterized by FT-IR, H-1-NMR and gel permeation chromatography (GPC) techniques. The results demonstrated that the degree of amination of the NH2-PEO-NH2 could be up to 1.95. The molecular weight of the PBLG-PEO-PBLG triblock copolymer could be adjusted easily by controlling the molar ratio of BZ-L-Glu NCA to the macroinitiator NH2-PEO-NH2.
