Abstract
Thermally conductive compositions include from about 20 wt. % to about 80 wt. % of a polycarbonate polymer, from about 0.5 wt. % to about 30 wt. % of an impact modifier, and a thermal conductivity modifier. The thermal conductivity modifier includes from about 0.5 wt. % to about 10 wt. % of a high density polyethylene polymer, from about 0.5 wt. % to about 10 wt. % of a maleic anhydride type copolymer, or from about 0.01 wt. % to about 10 wt. % of an acid component. In some aspects the thermally conductive compositions have a notched Izod impact strength of at least about 30 J/m, a through-plane thermal conductivity of at least about 0.4 W/mK and/or an in-plane thermal conductivity of at least about 1.0 W/mK. Methods for making the compositions and articles formed according to the methods are also described.
