| Abstract: | A novel macromonomer,polystyrene capped with thienyl group (PST Thp), which can undergos oxidation coupling polymerization,has been synthesized by anionic polymerization of styrene with butyl lithium as the initiator and 3 bromo thiophene as the terminator.Its homopolymerization and copolymerization with thiophene in the presence of anhydrous ferric chloride produced poly(thiophene g styrene) (PThp g ST) and were studied by GPC,FTIR and UV Vis spectroscopy.The homopolymerization just gave out polymacromonomer with very low polymerization degree.Copolymerization of PST Thp with thiophene produced graft copolymer with conjugated main chain of polythiophene and narrowly distributed branch chain of PST.Copolymerization conversion of PST Thp and the fraction of the soluble of PThp g ST increase with molecular weight of PST Thp. |
