In this paper, the influence of the amount of vulcanizator andrubber--plastic ratios on the dynamic mechanic properties of the dynamically vulcanized EPDM/PP blends was explored. The experiment showed that at the same temperature, dynamic modulus of blends and glass transition temperature (Tg) increased with the amount of vulcanizator. The dynamic modulus of blends increased and Tg′s of EPDM decreased with increasing resin content.%探讨了硫化剂用量、橡塑比对EPDM／PP共混物动态力学性能的影响。实验表明，在相同温度下，随着硫化剂用量增加，共混物的动态模量及EPDM的玻璃化温度(Tg)升高；随着树脂含量的增加，共混物的动态模量增大，EPDM的玻璃化温度降低。
