| Abstract: |
| The dielectric properties，i.e.dielectric constant εr and dielectric loss factor tanδ of black-filled rubber compound during vulcanization were determined and analysed by a completely filled short circuited waveguide technique.The results showed that εr increased as the crosslink density of rubber increased；the less black particle diameter，larger surface area and higher structure，the greater tanδ of rubber compound；at the same curing conditions，NR>BR>SBR>OEBR>OESBR in terms of εr. |
