Abstract: Disclosed is a composite from about 50 wt. % to about 90 wt. % of a thermoplastic resin, wherein the thermoplastic resin comprises a polycarbonate polysiloxane copolymer; and from about 10 wt. % to about 50 wt. % of a carbon-based filler. The composite exhibits a dielectric constant ε′ of between 5 and 20 and a dissipation loss ε″ of between 0.1 and 6, measured at frequencies between about 10 and 120 GHz.

Abstract: Provided are copolycarbonate compositions including a stabilizer package which comprise a phosphorous-containing acid, an ester of phosphorous-containing acid, and an organosulfonic stabilizer where the phosphorous-containing acid and the ester of a phosphorous-containing acid are present in a molar ratio of 1 to 2. The total stabilization package is for example, in the amount by weight of 4 to 32 ppm, 8 to 24 ppm, or 8 to 16 ppm and the organosulfonic stabilizer is, e.g., of 2 to 30 ppm, or 4 to 24 ppm, or 8 to 16 ppm.
