摘　　要：采用熔融挤出法制备了尼龙612/环氧树脂(EP)/苯乙烯-乙烯-丁二烯-苯乙烯嵌段共聚弹性体与马来酸酐接枝共聚物(SEBS-g-MAH)/聚碳酸酯(PC)共混合金,并研究了合金的力学性能及微观形态。结果表明:尼龙612/EP/SEBS-g-MAH/PC合金各组分质量比为75/2/9/25时,合金的冲击强度比纯尼龙612提高了278.7%,断裂伸长率提高116%。微观结构形态研究表明:合金分散相的尺寸减小、分布更加均匀。Nylon612/epoxy （EP）/styrene-ethylene-butadiene-styrene grafted maleic anhydride （ SEBS-g-MAH）/polycarbonate （PC） blends were prepared by melting extrusion molding. The mechanical properties and microscopic morphologies of blends were studied. The results showed that when the mass ratio of nylon612/EP/SEBS-g-MAH/PC was 75/2/9/25, the notched impact strength was 278.7% and the elongation at break was 116% higher than that of nylon 612. The microscopic morphology results showed that the size of discrete phase of blend decreased and the distribution was more even.
