A film extrusion composition includes specific amounts of a heat-resistant copolycarbonate, a slip agent, and a particulate crosslinked polymethylsilsesquioxane having particles of a specific size. An extruded film prepared from the film extrusion composition exhibits a beneficial balance of telescoping, blocking, and dielectric properties. The extruded film is useful for forming electrostatic film capacitors.

A composition includes specific amounts of a copolycarbonate and a roughening agent. The copolycarbonate contains first carbonate units derived from a first bisphenol monomer such that a homopolycarbonate of the first bisphenol monomer has a glass transition temperature less than 155° C., and second carbonate units derived from a second bisphenol monomer such that a homopolycarbonate of the second bisphenol monomer has a glass transition temperature of 155° C. or higher. The roughening agent includes a particulate crosslinked polymethylsilsesquioxane having a median equivalent spherical diameter greater than 5 micrometers and less than or equal to 10 micrometers.

A polycarbonate-polysiloxane includes specific amounts of first carbonate units having the structure wherein Ris a C-Cdivalent aromatic group, second carbonate units having the structure wherein Ris a C-Cdivalent aromatic group having the structure wherein R, R, R, R, R, R, X, j, m, n, x, and y are defined herein. The polycarbonate-polysiloxane is useful for forming thin extruded films, which in turn are useful for fabricating electrostatic film capacitors.
