摘要
用差示扫描量热法(DSC)考察了添加扩链剂进行反应性共混后PET/PBT的结晶熔融行为。共混体系的特性粘数随反应时间的增加先升后降,冷结晶温度随时间的增加逐渐升高。
By means of DSC, the effects of chain extender on the crystallization and melting behavior of PET/PBT blends were studied. It was shown that the intrinsic viscosity of blends increased firstly and then decreased. The cold crystallization temperature increased with blending time while the melt crystallization temperature and the melt point decreased.
