| 摘 要： | 以顺酐化三元乙丙橡胶（ＭＥＰＤＭ）为增容剂，研究了ＥＰＤＭ对聚甲醛（ＰＯＭ）的共混增韧生。结果表明，ＭＥＰＤＭ能明显改善ＰＯＭ与ＥＰＤＭ的相容性，使共混物分散相尺寸明显减少，分布更均匀，熔点和结晶度降低，缺口冲击强度提高。当ＰＯＭ／ＥＰＤＭ／ＭＥＰＤＭ（质量比）为８５／９／６时，共混物的缺口冲强度为１０．２ｋＪ／ｍ＾２。

| Abstract: | The blending of polyoxymethylene(POM) and EPDM was studied in order to improve the tonghness of POM with meleated EPDM(MEPDM) as compatibilizer.The results showed that MEPDM could improve the compatibility of POM and EPDM remarkably,the partical size and distribution of the dispersed phases in the blend could be controlled,the melting point and crystallinity of the blend decreased and the notched impact strength increased.When POM/EPDM/MEPDM was 85/9/6,the notched impact strength was 10.2 kJ/m2. |
