| Abstract: | Amphiphilic block copolymers with different molecular weight and low polydispersities was synthesized by atom transfer radical polymerization(ATRP) of styrene using MPEG-Br as a macroinitiator,which was obtained by easterification of poly(ethylene glycol) methyl ether with 2-bromoisobutyryl bromide.Its structure and "living" characterization were characterized by 1H-NMR、FT-IR、GPC. |
