聚(2,5-二甲基对苯乙炔)前聚物的合成及表征

Synthesis and Characterization of Poly(2,5dimethyl1,4phenylene1,2ethylene1diethylsulphonium chloride)

以对二甲苯为原料，经三步化学反应合成聚（２，５－二甲基－１，４－亚苯基－１′，２′－乙二撑－１′－氯化二乙锍盐），讨论了温度、气氛和溶剂对聚合反应的影响。

The precursor polymer of poly(2,5dimethylpphenylene vinylene)poly(2,5dimethyl1,4phenylene1,2ethylene1diethylsulphonium chloride) was synthesized by 3step reactions using pdimethylbenzene as raw material. Effect of temperature,atmosphere and solvent on the polymerization were discussed. The structure of the product was identified by IR and 1 H NMR.
