Abstract
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.
