Abstract: A film comprising a copolycarbonate, wherein the film is a uniaxially-stretched, extruded film comprising at least one film region having: an average thickness of more than 0 and less than 14 micrometers with a standard deviation of 0.8 micrometer to 1.6 micrometers, a surface having a surface roughness average of less than 0.04 micrometer as measured by optical profilometry, a dielectric constant at 1 kHz and room temperature of at least 2.7, a dissipation factor at 1 kHz and room temperature of 1% or less, and a breakdown strength of at least 620 Volt/micrometer; and the copolycarbonate has a Tg of greater than 180° C. and comprises carbonate units derived from a bisphenol compound of the formula (3).
