应用动态热力学分析仪测定了动态硫化EPDM /PP共混物的动态力学行为、Tg峰的变化,表明PP的非晶部分与EPDM具有部分互溶性, 同时讨论了共混物动态模量的特点。研究了不同橡塑比、硫化剂和软化剂用量对动态硫化EP DM/PP共混物动态力学性能的影响。

Dynamic mechanical behaviors of dynamically vulcanized EPDM/PP blends were measured by dynamic thermal mechanical analyser. The changes of Tg-peaks in various compositions shows that uncrystal part of PP and EPDM is partial miscible. Characteristics of dynamic modulus of the blend was discussed also. Effects of different ratio of rubber to plastics, am ount of the curing agent and the softening agent on dynamic mechanical propertie s of EPDM/PP blends were studied.
