Abstract: Thermoplastic compositions include: (a) from 10 wt % to 95 wt % of a polycarbonate component: (b) from 0.1 wt % to 50 wt % of a reinforcing filler: (c) from 0.1 wt % to 10 wt % of an impact modifier component having a linear polymer structure; and from 0.1 wt % to 10 wt % of a hydrocarbon additive. A weight percent ratio of the hydrocarbon additive to the impact modifier in the composition is 1:1 or lower. The hydrocarbon additive may include saturated carboxylic and acyclic structures. In particular aspects the impact modifier component has a linear, non-polarized polymer structure, and the composition has improved Izod impact properties and/or gloss properties as compared to a reference composition that includes a polarized impact modifier instead of the impact modifier component.
