摘要

The radical copolymerization of methyl methacrylate and 2-hydroxyethyl methacrylate was carried out via atomtransfer radical polymerization (ATRP) initiated by ethyl 2-bromoisobutyrate and catalyzed by CuBr/2

2'-bipyridinecomplex. This polymerization proceeds in a living fashion with controlled molecular weight and low polydispersity. Theobtained copolymer was esterified with 2-bromoisobutylryl bromide yielding a macroinitiator

poly(methyl methacrylate-co-2-hydroxyethyl methacrylate-co-2-(2-bromoisobutyryloxy)ethyl methacrylate)

and its structure was characterized by 1H-NMR.This macroinitiator was used for ATRP of styrene to synthesize poly(methyl methacrylate)-graft-polystyrene.The molecular weight of graft copolymer increased with the monomer conversion

and the polydispersity remained relatively low.The individual grafted polystyrene chains were eleaved from the macroinitiator backbone by hydrolysis and the hydrolyzed product was characterized by 1H-NMR and GPC.
