聚碳酸酯的热降解试验是在降解炉中进行的。采用粘度法、热重—差热分析法(TG—DTA)和傅立叶红外光谱(FTIR)测定其热氧稳定性。通过测试、理论计算和降解机理的分析,从而较为深入地揭示了聚碳酸酯的热氧降解行为。
Polycarbonate thermal degradation test is carried out in the degradation furnace. The thermo-oxidative stability was measured by viscosimetry, TG-DTA and FTIR. Through the analysis of the test, the theoretical calculation and the degradation mechanism, the thermal oxygen degradation behavior of the polycarbonate is revealed more deeply.
