摘　　要：选择SEBS g MA和两种不同的小分子增塑剂DIDP、BSBA ,采用共混挤出的方法 ,制备了尼龙 12 12(PA12 12 ) /SEBS g MA/DIDP/BSBA共混合金 ,并对其力学性能进行了研究。结果表明 ,随着SEBS g MA质量分数的增加 ,共混合金的冲击强度明显提高。当SEBS g MA质量分数为 10 %时 ,其缺口冲击强度为 89 3kJ/m2 ,是PA12 12的 2 0倍左右 ;拉伸强度保持率是PA12 12的 90Two kinds of different plasticizers DIDP/BSBA and toughening agent SEBS g MA were used in the preparation of nylon1212/SEBS g MA/DIDP/BSBA blends by means of blending extrusion, and the mechanical properties of the prepared blends were studied The results indicated that the notched Izod impact strength enhanced obviously with the increase of the mass fraction of SEBS g MA When the mass fraction of SEBS g MA was up to 10%, the notched Izod impact strength was 89 3 kJ/m 2, which was about 20 times as large as that of pure nylon1212, and the tensile strength was 0 9 times of that of nylon1212
