酯交换反应对PBT／PC共混体系相容性及热行为的影响

Esterification Reaction Between PBT and PC and Its Effect on the Misbility and Thermal Behavior of PBT/PC Blends

摘要: 研究了ＰＢＴ、ＰＣ间的酯交换反应及共混体系的相容性和热行为。ＩＲ结果表明，在熔融共混过程中ＰＢＴ、ＰＣ间发生了酯交换反应，磷酸三苯酯可在一定程度上抑制酯交换反应的进行，但是当温度过高或共混时间过长时，ＴＰＰ的作用减弱甚至消失。

Abstract: In this paper, the esterification reaction between PBT and PC and its effect on the compatibility and thermal behavior of PBT/PC blends were investigated by using IR, DSC and TGA. The results indicated that the esterification between PBT and PC occurred d
