采用 Ｒ Ｓ Ｍ Ａ 为增容剂制备了 Ｐ Ａ６／ Ｐ Ｐ共混物，研究了 Ｒ Ｓ Ｍ Ａ 增容 Ｐ Ａ６／ Ｐ Ｐ共混物的形态结构和热行为以及晶态结构，并探讨 Ｒ Ｓ Ｍ Ａ 增容 Ｐ Ａ６／ Ｐ Ｐ共混物的增容机理。结果表明， Ｐ Ａ６／ Ｐ Ｐ共混物为热力学不相容的海岛型两相结构， Ｒ Ｓ Ｍ Ａ 的加入改善了 Ｐ Ａ６ 与 Ｐ Ｐ相间的相容性，使两相分散均匀，分散度提高。 Ｒ Ｓ Ｍ Ａ 对 Ｐ Ａ６／ Ｐ Ｐ共混物的增容机理可用界面分散相复合模型描述。
P A6 / P P blends were prepared using R S M A as compatibilizer. The morphology, thermal behavior and crystalline structure of R A M A compatibilized P A6 / P P blends were studied. The effects of R S M A compatibilization Mechanism of compatibilization of P A6 / P P blends. The results show that the P A6 / P P blend is a thermodynamically incompatible sea island two-phase structure. The addition of R S M A improves the compatibility between P A6 and P P phases, and disperses the two phases uniformly. improve. The compatibilization mechanism of R S M A to P A6 / P P blends can be described by a composite interface-dispersion model.
