聚碳酸酯的热降解

Thermal degradation of polycarbonate

综述了聚碳酸酯的热稳定性及其影响因素,并详细论述了一些添加剂如偶联剂甲基三甲氧基硅烷、钛酸四丁酯、阻燃剂二苯砜磺酸钾(KSS)、聚氨丙基苯基倍半硅氧烷(PAPSQ)等对聚碳酸酯热稳定性的影响,阐述了Kissinger法和Ozawa法等聚合物热降解动力学的分析方法。重点介绍了近期国内外有关聚碳酸酯热降解产物和热降解机理方面的研究成果。

This paper introduces the thermal stability of polycarbonates （PC） and its affecting factors. The effect of some additives, such as coupling agent： methyltrimethoxy silane and tetrabutyl orthotitanate, flame retardant： potassium diphenylsulfone sulfonate （KSS） and poly（aminopropylphenylsilsesquioxane） （PAPSQ） on the thermal stability of PC are discussed. The analytical methods of the decomposition kinetics of the polymer： Kissinger method and Ozawa method are introduced. The recent researches and major results in the thermal degradation mechanism of PC are reviewed.
