| 中文摘要 | a novel structural triblock copolymer of poly(gamma-benzyl-l-glutamic acid)-b-poly(ethylene oxide)-b-poly(epsilon-caprolactone) (pblg-peo-pcl) was synthesized by a new approach in the following three steps: (1) sequential anionic ring opening polymerization (rop) of ethylene oxide and epsilon-caprolactone with an acetonitrile/potassium naphthalene initiator system to obtain a diblock copolymer cn-peo-pcl with a cyano end-group; (2) conversion of the cn end-group into nh2 end-group by hydrogenation to obtain nh2-peo-pcl; (3) rop of gamma-benzyl-l-glutamate-n-carboxyanhydrides (bz-l-glunca) with nh2-peo-pcl as macroinitiator to obtain the target triblock copolymer. the structures from cn-peo precursor to the triblock copolymers were confirmed by ft-ir and h-1 nmr spectroscopy, and their molecular weights were measured by gel permeation chromatography. the monomer of bz-l-glunca can react almost quantitatively with the amino end-groups of nh2-peo-pcl macroinitiator by rop. |
