摘要
利用F lynn-W a ll-O zaw a方法,对纤维用聚酯(PET)及二羧乙基苯基氧化磷(BCPO)改性的阻燃聚酯(FR-PET)的热失重(TG)降解行为进行了研究,发现聚酯和阻燃聚酯的热降解过程相近,热降解活化能没有较大的变化,阻燃剂BCPO的引入对热降解过程无显著影响。
Thermal degradation activation energy of poly (ethylene terephthalate) (PET) and phosphorus-containing flame retardant copolyester (FR-PET) were investigated by thermogravimetric analysis (TG) according Flynn-Wall-Ozawa method. It is founded that there is not much difference between the values of thermal degradation activation energy of PET and FRPET, which suggests that the incorporation of flame retardant BCPO does not greatly influence their thermal degradation processes.
