ABSTRACT:
A dielectric capacitor having self healing properties is disclosed. The capacitor includes a film made of an amorphous aromatic copolycarbonate having a weight average molecular weight of at least 10,000 and a glass transition temperature of at least 160° C. In a preferred embodiment the copolycarbonate includes structural units derived from bisphenol TMC. Also disclosed is a process for making the film.
