摘要

Poly(methyl acrylate)-b-poly(5

6-benzo-2-methylene-1

3-dioxepane) (PMA-b-PBMDO) was synthesized by two-step atom transfer radical polymerization (ATRP). Firstly

ATRP of methyl acrylate (MA) was realized using ethyl α-bromobutyrate (EBrB) as initiator in the presence of CuBr/2

2'-bipyridine. After isolation

poly(methyl acrylate) withterminal bromine (PMA-Br) was synthesized. Secondly

the resulting PMA-Br was used as a macromolecular initiator in theATRP of BMDO. The Structure of block copolymer was characterized by 1H-NMR spectroscopy.Molecular weight and molecular weight distribution were determined on a gel permeation chromatograph(GPC).
