| 摘 要： | 用马来酸酐（ＭＡＨ）熔融接枝聚乙烯（ＬＤＰＥ）和三元乙丙胶（ＥＰＤＭ）改善了与基体ＰＡ－６６的相溶性，继而大幅度地提高了ＰＡ－６６／（ＰＥ）／ＥＰＤＭ）－ｇ－ＭＡＨ的冲击强度。当共混物中ＥＰＤＭ－ｇ－ＭＡＨ为９％、ＰＥ－ｇ－ＭＡＨ为３０％时，共混材料的冲击强度是ＰＡ－６６的３．３５倍，成本降低约１５％。同时对增韧机理进行了分析

| Abstract: | Maleicanhydride grafted with LDPE and EPDM was studied. The compatibility between PA-66 and PE-EPDM could be improved by (PE/EPDM)-g-MAH. The impact strength of PA-66/(PE/EPDM)-g-MAH blends could be increased apparently. The impact strength of blends is three times than that of PA-66. The cost was reduced 15 %. The toughening mechanism was analysed simulataneously. |
