| 中文摘要 | a new asymmetric h-shaped block copolymer (ps)(2)-peo-(pmma)(2) has been designed and successfully synthesized by the combination of atom transfer radical polymerization and living anionic polymerization. the synthesized 2,2-dichloro acetate-ethylene glycol (dcag) was used to initiate the polymerization of styrene by atrp to yield a symmetric homopolymer (cl-ps)(2)-chcccch2ch2oh with an active hydroxyl group. the chlorine was removed to yield the (ps)(2)-chcooch2ch2oh ((ps)(2)-oh). the hydroxyl group of the (ps)(2)-oh, which is an active species of the living anionic polymerization, was used to initiate ethylene oxide by living anionic polymerization via dpmk to yield (ps)(2)-peo-oh. the (ps)(2)-peo-oh was reacted with the 2,2-dichloro acetyl chloride to yield (ps)(2)-peo-occhcl2 ((ps)(2)-peo-dca). the asymmetric h-shaped block polymer (ps)(2)-peo-(pmma)(2) was prepared via atrp of mma at 130 degrees c using (ps)(2)-peo-dca as initiator and cucl/bpy as the catalyst system. the architectures of the asymmetric h-shaped block copolymers, (ps)(2)-peo-(pmma)(2), were confirmed by h-1 nmr, gpc and fr-ir. |
