| 摘 要： | 本文研究了PC/PET熔融共混体系组分比和酯交换反应对共混物形态、结构和性能的影响。结果表明:随PET含量增加,体系中两个组分的互容性增加。酯交换反应可以增大两个组分的互容性。加入催化剂所引起的酯交换反应改变了共混物的结构,使共混物的力学性能有所下降。

| Abstract: | In this paper the effects of composition and transesterification on morphology, structure and properties are studied in PC/PET melting blend system. The result shows : with the increase of PET contents, the compatibility increases. Transesterification can enhance the compatibility of two components. The transesterification, caused by the addition of catalyst, affects the structure of blends and the mechanical properties of blends decrease. |
