Patent number: 8218291Abstract: A monomer and polycarbonate resin are provided, as are methods of making the monomer. The resin may be used to provide a thin film that has a higher dielectric constant and higher glass transition temperature, and similar breakdown strength and similar dissipation factor to films prepared from polycarbonate resins not so modified. The thin films, in turn, may advantageously be used to form, wholly or in part, articles such as capacitors, sensors, batteries, flexible printed circuit boards, keyboard membranes, motor/transformer insulations, cable wrappings, industrial tapes, interior coverage materials, and the like. In particular, a capacitor comprising the polycarbonate resin is also provided.Type: GrantFiled: March 31, 2010Date of Patent: July 10, 2012Assignee: General Electric CompanyInventors: Norberto Silvi, Gary Charles Davis, Patrick Joseph McCloskey, Sheldon Jay Shafer, Julia Lam Lee, Yang Cao, Patricia Chapman Irwin
