Abstract

This invention relates to polycarbonate compositions and articles comprising the same. The polycarbonate compositions comprise the following components: A) from 75 wt.-% to 97.5 wt.-% of a polycarbonate, B) from 1.5 wt.-% to 15 wt.-% of a flow promoter selected from alicyclic hydrocarbon resins, and C) from 1 wt.-% to 15 wt.-% of an impact modifier, in each case based on the total weight of the composition; wherein the composition comprises no polycarbonate-polysiloxane copolymer. The polycarbonate compositions of the present invention have good coating resistance, chemical resistance and impact properties as well as better flowability.
