Influence of imidazole catalysts on electrical properties of epoxy resins cured with acid anhydride

In this paper, electrical properties such as dissipation factor (tan /spl delta/) and conductivities of acid anhydride-cured epoxy resins added with imidazole catalysts are discussed in a wide range of temperature and frequency. The relationship between electrical properties and concentrations and structures of imidazole catalysts is also discussed.
