摘　　要：以聚碳酸酯(PC)、丙烯腈–丁二烯–苯乙烯塑料(ABS)为主体材料,以苯乙烯、丙烯腈、甲基丙烯酸缩水甘油酯三元共聚物(SAG–002)和甲基丙烯酸甲酯、苯乙烯、有机硅组成共聚物(S-2001)为增容剂,通过熔融混合挤出制得PC/ABS合金。对PC/ABS合金的力学性能、流动性能、热性能进行测试和分析,采用差示扫描量热(DSC)仪观察两种增容剂对PC/ABS合金玻璃化转变温度的影响,并讨论了增容剂在PC/ABS合金中的作用机理。研究发现,在增容剂SAG–002用量为2份时,随PC含量的增加,PC/ABS合金的力学性能随之提高;增容剂S-2001在该PC/PBT合金中有明显的增韧作用;在PC/ABS(质量比为80/20)中,加入2份增容剂SAG-002和4份的增容剂S-2001,PC/ABS合金的相容性达到最佳状态。PC/ABS alloy was prepared by melt mixing and extrusion with PC and ABS as resin matrix,styrene-acrylonitrile-glycidyl methacrylate copolymer （SAG002） and methyl methacrylate-styrene-organosilicone copolymer（S2001） as compatibilizer. The mechanical,fluidity,thermal properties of the PC/ABS alloy were characterized and analyzed. The effects of compatibilizers with different contents of glass transition temperature of PC/ABS alloy were measured with DSC. Furthermore,the compatibility mechanism of the compatibilizers in the PC/ABS alloy was discussed. The test results show the mechanical properties of the PC/ABS alloy is strengthened with increasing PC content in PC/ABS alloy after adding compatibilizer（SAG-002） with its content being two phr. The compatibilizer（SAG-002） has an obvious toughening action for PC/ABS alloy. The PC/ABS alloy shows the best compatibility,which is composed of 80%PC and 20%ABS with adding two phr SAG-002 and four phr S-2001.
