摘要
研究了2,6-萘二甲酸作为共聚第三组分和对苯二甲酸与乙二醇进行共聚的酯化、缩聚动力学,分析了共聚酯的热性能、结晶性能及二氧化硅在共聚酯中的分散性能。在工业化装置上进行了合成试验,成功生产出共聚酯切片并进行了工业化拉膜试验,对制成的薄膜分析其性能以满足电容器用聚酯薄膜的要求。
The esterification and polycondensation kinetics of using 2,6-naphthalic acid as the third reactive component in copolycondensation with pure-terephthalic acid and ethylene glycol are studied. At the same time, the thermal behaviors and crystaUinity of the copolyester and the dispersion of SiO2 in it are also discussed. Through the synthetic test of the copolyester on industrial plant, the co-PET chips has been produced and later industrialized film-stretching test was carried out successfully. Based on all the analysis, the co-PET films can meet the demands of capacitor used PET film.
