摘　　要：以SEBS为增韧剂对PA6进行增韧改性 ,研究了SEBS的用量和处理方法对PA6性能的影响以及充油SEBS g MAH对不同牌号PA6性能的影响。结果表明 ,PA6的冲击韧性随SEBS用量的增加而提高 ,尤其是充油SEBS g MAH的加入 ,使共混物的韧性及伸长率得到明显改善 ,当充油SEBS g MAH的质量分数为 10 %时 ,体系的常温缺口冲击强度是纯PA6的 6倍。SEBS的熔融接枝过程中 。PA6 was toughened with SEBS as toughening agent.The effect of SEBS content on the property of PA6,and the effect of oil-extended SEBS-g-MAH on the properties of different types of nylon were studied.The results indicated the impact property of PA6 was improved with the increase of SEBS content,especially when oil-extended SEBS-g-MAH was used,the impact property and elongation rate were improved obviously.When the content of oil-extended SEBS-g-MAH was 10%,the notched impact strength at atmospheric temperature was 6 times as high as that of pure PA6.Strict control of extrusion temperature and revolution during the melting graft was the key in the toughening modification.
