摘要: 研究了聚碳酸酯与ABS(PC/ABS)及PC/ABS与马来酸酐接枝聚乙烯共聚物(PC/ABS/PE-g-MAH)共混体系的力学性能和应力开裂性能。用DSC和SEM研究了共混体系的相容性。结果表明:ABS的加入能提高PC的冲击强度,ABS的含量及品种影响PC/ABS合金的力学性能,ABS能提高PC的耐溶剂应力开裂性能。PC/ABS/PE-g-MAH共混体系的力学性能和相容性优于PC/ABS共混体系,Abstract: The mechanical properties and stress crack properties of PC/ABS and PC/ABS/PE g MAH blends were studied. Adding ABS could increase the impact strength of PC, the content and kinds of ABS can affect the mechanical properties of the blends. ABS can also
