Abstract: The corona deterioration of a polycarbonate in dry air based on the I. E. C. method was investigated by the weight change, dielectric characteristics and infra-red spectrum. As you know, polycarbonate is a excellent electrical insulating material. No changes have observed on the dielectric characteristics of the polycarbonate by radioactive irradiation. Author obtained that the dielectric loss and constant of the corona irradiated specimens increase gleatly and the hydroxyle(-OH) absorption increases with corona radiation. The degradation of the dielectric characteristics of the corona irradiated polycarbonate is explained by introduction of new produced polor radicals, as hydroxyle group.
