本文通过添加新的增容剂，对PET/芯-壳共聚物体系进行了共混改性，并考查了增容剂对共混物相形态及力学性能的影响，结果表明：该增容剂能大大改善共混体系各组份之间的相容性，并大幅度提高共混物的缺口冲击强度。
In this paper, a new compatibilizer was added to modify the PET / core-shell copolymer system. The effects of compatibilizer on morphology and mechanical properties of the blend were investigated. The results show that the compatibilizer Can greatly improve the compatibility between the components of the blend system, and greatly improve the notched impact strength of the blend.
