-
The reaction conditions for preparing the organic soluble precursor polymer of poly(2,5-dimethoxy phenylene vinylene) have been examined. The results indicated that NaOH was an effective initiator for this polymerization. The optimum reaction conditions were as follows: 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 petroleum ether can effectively increase the monome,conversion and precursor polymer yield. The structure of the polymer precursor were characterized by IR, UV-Vis,1H NMR,TGA and DSC.
