Abstract

A condenser dielectric comprises a film of thermoplastic resinous material containing polyvinyl carbazole having small mica flakes embedded therein, the film having a thickness of less than 10 mils. The resinous material may be polyvinylcarbazole itself or copolymers of vinylcarbazole and styrene, diallyl phthalate or glycol dimethacrylate and may be plasticized with wax. The polyvinylcarbazole may be purified by dissolving in benzene or toluene and precipitating with methyl alcohol or by adding activated charcoal and fuller's earth to the solution, filtering and evaporating the solvent. Specification 463,085 is referred to.
