摘要
通过差示扫描量热法(DSC)和热重分析法(TGA),测试了两种不同的纤维级聚苯硫醚(PPS)树脂的结晶和热分解过程,并用Khanna法、Ozawa法和Jeziorny法分析了两种PPS的非等温结晶动力学性质。结果表明:Ozawa方程、Jeziorny方程都可以很好地描述PPS的非等温结晶过程,并求出了相应的动力学参数;比较了两种PPS热性能之间的差异,认为相对分子质量影响PPS的热性能。
The non-isothermal crystallization and thermal degradation ot various fiber-grade polyphenylene sulfide （PPS） were investigated via differential scanning calorimetry （DSC） and thermogravimetrie analysis （TGA）, and the non-isothermal crystallization of two kinds PPS were analyzed by Khanna, Ozawa and Jeziorny method. The results indicated that either of Ozawa and Jeziorny method made a good description of the non-isothermal crystallization process, calculated the relevant kinetic parameters, compared the thermal diversities of two kinds PPS and the thermal property of PPS was dependant on relative molecular weight markedly.
