Poly (p-phenylene vinylene) (PPV) was synthesized from p-xylylene bis(tetrahydrothiophenium chloride) using the Wessling route and characterized by Fourier Transform Infra-Red (FTIR) and UV-visible (UV-VIS) spectroscopic techniques. The significance of thermal treatment along with evolution of precursor polymer to polymer PPV was also studied through these spectroscopic techniques. Thermally Stimulated Current (TSC) measurements indicated the presence of crystallization, sulphonium group which occurred through the evolution from precursor polymer to polymer PPV during thermal treatment.
聚对苯撑乙烯（PPV）通过韦斯林路线由对二甲苯双（四氢噻吩鎓氯化物）合成，并采用傅里叶变换红外（FTIR）和紫外可见（UV-VIS）光谱技术进行表征。还通过这些光谱技术研究了热处理以及前体聚合物向聚合物PPV演变的重要性。热刺激电流（TSC）测量表明在热处理过程中，从前体聚合物向聚合物PPV演变过程中出现了结晶和锍基团。
