Abstract

Reverse atom transfer radical polymerization RATRP of styrene S was carried out in bulk using polyazoester prepared by the reaction of polyethylene glycol with molecular weight of 3000 and 44′azobis4cyanopentanoyl chloride as initiator and CuCl2/22′bipyridine bpy catalyst system to yield polyethylene glycolbstyrene block copolymer The block copolymers were characterized 1H NMR FTIR spectroscopy and GPC The 1H NMR and FTIR spectra showed that formation of polyethylene glycolbstyrene block copolymer The polydispersities of block copolymers were observed between from 149 and 198 GPC measurements
