Author(s): Jubaraj Chandra, Homayun Kabir, Roushown Ali and Tariqul Hasan
Abstract: Azide end-functional initiator 1-azidoethane-2-oxy-2-bromopropionyl (AEOBP) was synthesized by esterification of 2-azidoethanol and 2-bromopropionyl bromide in presence of triethylamine (Et3N) in dry Tetrahydrofuran (THF). Azido end-functional polystyrene (PS-N3)) was synthesized by AEOBP initiated CuBr/bipyridine mediated Atom Transfer Radical Polymerization (ATRP) technique with controlled molecular weight and narrow polydispersity. The yield and molecular weight of polystyrene increased with increasing styrene/AEOBP ratio and reaction temperature. The structures of the polystyrene and AEOBP initiator were characterized by 1H NMR spectra and the molecular weight of the polystyrene was determined by Gel Permeation Chromatography (GPC).
