Abstract: Poly(ethylene oxide) containing azogroups(pre-PEO) was prepared by reacting azoisobutyronitrile (AIBN) with poly( ethylene glycol ) (PEG). The molecular weight of pre-PEO was depended on the reaction time, the ratio of PEG to AIBN and the molecular weight of PEG. Pre-PEO decomposed in the presence of butylacrylate (BA) monomer to form poly ethylene oxide block butylacrylate copolymers(PEO-b-PBA). The molecular weights of PEO-b-PBA and the homopolymer of PBA were proportional to the ratio of BA to pre-PEO. The purified block copolymers were charactherized using IR, 1H NMR and GPC.
