| Abstract: |
| The rhrtological properties of VMQ/EPDM compounds with different blending ratio were determintd by Monsanto rheometer；the proportions of carbon black in two phases of blends were determined by net-cage extraction；the influence of mill run number on the bulk resistance of blend vulcanizatts was investigared；the morphology of vulcanizates wsa studied by TEM.The results showed that the VMQ/EPDM vulcanizates with proper blending；ratio and carbon black level possessed high conductivity because of their obvious “sea-island” structure with quite different viscosity and carbon black proportion in two phases of blends；the VMQ/EPDM blends with a blending ratio of 80/20-70/30 showed the optimum conductivity and processibiliry. |
