✦ Synopsis
Polyetherimide is an amorphous thermoplastic resin with a high glass transition temperature. It is characterized by high heat resistance and mechanical properties, which make it suitable for industrial application. Two di †erent polyetherimides (varying by chemical formula) were investigated, in terms of their dielectric strength and space charge behaviour. The comparison reveals important variations in the electric properties.

A deterministic treatment is presented of the statistical nature of the breakdown of passive films on metal surfaces, in which it is assumed that breakdown sites on the surface are normally distributed in terms of the cation vacancy diffusivity (D) or log D. This analysis, which is based on the poin
