摘要
研究了反应挤出型低硬度EPDM/PP共混型热塑性动态硫化橡胶（EP－TPV）胶相交联密度和平均胶相粒径对力学性能和流变性能的影响。结果表明，要想制得综合性能优良的EP－TPV，应通过制备工艺控制，使EP－TPV具有适中的胶相交联密度及适中的平均胶相粒径。
The effects of rubber phase crosslinking density and average rubber particle diameter on mechanical and rheological properties of low hardness EPDM/PP blend thermoplastic dynamic vulcanizates(EP－TPV) prepared by reactive extrusion dynamic vulcanization were studied. It was concluded that，in order to prepare EP－TPV with excellent mechanical and rheological properties，moderate rubber phase crosslinking density and average rubber particle diameter by means of preparation technology control，were advisable.
