| 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 improve the resistance against solvent stress crack properties of PC. By DSC and SEM, we studied the compatibility of the two blend systems. The mechanical properties and the miscibility of PC/ABS/PE g MAH system are better than PC/ABS system. The compatibility between two phases in the PC/ABS blends could be improved by adding PE g MAH as a compatibilizer. |
