| Abstract: | In this paper,thermosets of three epoxy resin cured by methyl tetrahydrophthalic anhydride and modified anhydride made themself respectively were prepared and theirs electrical properties such as,volume resistance,surface resistance and tangent of dielectric loss angle had been determined under the different hot/wet environments.The results showed that the electrical properties of bisphenol A based epoxy resin cured by modified anhydride wene better than any others. |
