Zusammenfassung:A composition includes 65.0-99.85 wt % of a high heat copolycarbonate, the high heat copolycarbonate further having a number ratio of carbon atoms to a total of hydrogen, oxygen, and fluorine atoms of less than 1.12, preferably from 0.83 to less than 1.12; 0.05-0.5 wt % of a first roughening agent; and 0.1-15.0 wt % of an organic slip agent, wherein the organic slip agent comprises pentaerythritol tetrastearate, dipentaerythritol hexastearate, glycerol tristearate, high density poly(ethylene), polymethylpentene, a poly(carbonate-siloxane), or a combination thereof; wherein each amount is based on the total weight of the composition and totals 100 wt %.
