摘要
通过差示扫描量热法研究了聚对苯二甲酸丁二酯/聚对苯二甲酸乙二酯(PBT/PET)共混体的热性能,发现PBT和PET熔点随各自组成的下降而下降。按Scott方程算出在220℃相互作用参数x=-0.064。PBT/PET共混体在所有组成范围内只出现一个T_g。
The heat behavior of Poly(butylene terephthalate) / Poly (ethylene terephthalate) (PBT/ PET) blends was studied by the differential scanning calorimeter (DSC). The melting point of PBT or PET decreased with the reduction of their individual composition. The interaction parameter x calculated according to scott's equation was -0.064 at 220℃, there was only one Tg for the PBT/PET blends over all composition.
