聚碳酸酯的热行为--《高分子材料科学与工程》2003年03期
The thermal behavior of polycarbonates under programmed heating conditions has been studied by in suit, FT IR, TG, GC MS, self made pyrolysis IR methods. The result shows that polycarbonates are stable below 300 ℃. The range of degradation temperature is from 460 ℃ to 500 ℃, and the main degradation products are phenol, p cresol, p ethyl phenol, p isopropyl phenol, bisphenol A, carbon monoxide and carbon dioxide. 【Keyword】: polycarbonates(PC) ; in situ FT IR ; TG ; thermal degradation ; pyrolysis mechanism
