POLYCARBONATE COPOLYMER AND ASSOCIATED FILM EXTRUSION COMPOSITION, EXTRUDED FILM, AND CAPACITOR

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...

Zusammenfassung: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.
