摘　　要：研究了相容剂丙烯腈-丁二烯-苯乙烯共聚物接枝马来酸酐共聚物(ABS-g-MAH)对聚碳酸酯/丙烯腈-苯乙烯-丙烯酸酯共聚物(PC/ASA)合金力学性能、热性能以及微观形貌的影响。结果表明,随着ABS-g-MAH用量的增加,PC/ASA合金的缺口冲击强度和拉伸强度先增加后减小,维卡软化点温度、分解温度以及玻璃化转变温度均降低。通过扫描电子显微镜(SEM)观察发现,ABS-g-MAH能够明显改善PC/ASA合金的相容性。The influences of ABS-g-MAH on the mechanical properties, heat- resistant properties, morphology of fractured surface of PC/ASA were studied. The re- sults show that the notched impact strength and tensile strength increase and then de- crease with the increasing of the content of ABS-g-MAH. The Vicat softening point, decomposition temperature, the glass transition temperature decrease with the increasing of the content of ABS-g-MAH. The result of SEM analysis shows that the compatibili- ty of PC/ASA alloy is improved by ABS-g-MAH.
