摘要
本文研究了尼龙－６６（ＰＡ－６６）与聚乙烯（ＬＤＰＥ）共混物的力学性能。结果表明，用马来酸酐接枝聚乙烯和三元乙丙橡胶（ＥＰＤＭ）改善了与基体ＰＡ－６６的相容性。添加弹性体ＥＰＤＭ，使之生成（ＰＥ／ＥＰＤＭ）－ｇ－ＭＡＨ共聚物，可以大幅度度地提高ＰＡ－６６／（ＰＥ／ＥＰＤＭ）－ｇ－ＭＡＨ冲击强度，同时熔体粘度随温度的变化趋于平缓，吸水率有所下降。
The mechanical properties of PA-66 and PE blends were studied in this paper. It showed that the compatibility among PA-66 and PE and EPDM could be improved by(PE/EPDM)-g-MAH.The impact strength of PA-66/ (PE/EPDM )-g-MAH copoiymer. At the same time molten viscosity tended to be steady with the temperature changing and moisture obsorption was reduced sightly.
