摘要
本文用热重分析法及粘度降法研究了PET与有色共聚醚酯共混物的热氧化降解动力学。发现在共聚醚酯合成过程中添加带有官能团的染料能提高共聚醚酯的热氧化稳定性,并从反应机理上对这一现象进行了初步探讨。
This paper studies the kinetics of thermooxidative degradation of polyblend comprising of PET and colored poly (ester-ether), by using thermo-gravimetric analysis and viscosity degradation methods. It is found that the thermooxidative stability of poly (ester-ether) can be improved when dyes with functional groups are added during its polymerization, Explorations are made based on the reactional mechanism.
