Abstract

Abstract: The reaction conditions for preparing the organic soluble precursor polymer of poly (2,5-dimethoxy phenylene vinylene)have been examined.The results indicated thatNaOH was an effective initiator for this polymerization,The optimum reaction conditionswere as follovvs:molar ratio of monomer to NaOH 1:1;concentration of monomer 0.05 to 0.2mol/L;polymerization time 2 hours and temperature below 5℃,Hexane and petroleumether can effectively increase the monomp,conversion and precursor polymer yield.Thestructure of the polymer precursor were characterized by IR, UV-Vis,¹H NMR,TGA andDSC.

Key words: conductive pnfymer, poly(dimethoxy phenylene vinylene), precursor polymer, synthesis
