ABSTRACT:
High impact mineral filled polycarbonates are comprised of a polycarbonate resin of a novaculite mineral filler having an average particle size of less than 5 microns. The percentage of novaculite is based on the total weight of the polycarbonate resin and novaculite. The polycarbonate articles formed from the mineral filled blends exhibit excellent impact properties over typical fillers for polycarbonate resin. Impact properties of the polycarbonate can be further improved by the addition of a silane coupling agent to the polycarbonate novaculite blend.
