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-p-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.
