摘　　要：以聚己内酰胺（PA6）、丙烯腈-丁二烯-苯乙烯共聚物（ABS）为主体材料，以丙烯腈-苯乙烯共聚物接枝马来酸酐物（AS-R-MAH）、甲基丙烯酸甲酸-丁二烯-苯乙烯共聚物接枝马来酸酐物（MBS-g-MAH）为相容剂，通过采用熔融混合挤出获得ABS／PA6合金。对该合金的力学性能进行测试和分析，讨论PA6，ABS，AS-g-MAH和MBS-g-MAH用量对ABS／PA6合金力学性能的影响规律，并观察了AS-g-MAH和MBS-g-MAH改性ABS／PA6合金的微观结构。结果表明，AS-g-MAH对ABS／PA6合金有一定增强作用，MBS-g-MAH对ABS／PA6合金有增韧作用。扫描电镜结果表明，当在100份ABS／PA6合金中添加6～8份MBS-g-MAH时，MBS-g-MAH在ABS／PA6合金中形成了带蜂窝结构的弹性体网络。The ABS/PA6 alloy was prepared by melt mixing and extrusion with PA6 and ABS as matrix resin, AS-g-MAH and MBS-g-MAH as compatibilizer. The mechani- cal properties of the ABS/PA6 alloy were tested and analyzed. The effects of contents of PA,ABS,AS-g-MAH and MBS-g-MAH on mechanical properties of the ABS/PA6 alloy were discussed. Furthermore, the microstructure of the ABS/PA6 alloy modified by AS- g-MAH and MBS-g-MAH was observed. The results show that the AS-g-MAH has strengthening action on ABS/PA6 alloy, and MBS-g-MAH has toughening action on ABS/ PA6 alloy. In addititon, the scan electron microscope （SEM）results indicate that MBS-g- MAH forms into elastomer network with honeycomb structures in the ABS/PA6 alloy when 6-8 phr MBS-g-MAH is added into 100 phr ABS/PA6 alloy.
