Abstract
Mineral filled poly(butyleneterephthalate)s are comprised of a poly(butyleneterephthalate) resin and 10 to 50 percent by weight of a novaculite mineral filler having an average particle size of less than 5 microns. Articles molded from the novaculite filled poly(butyleneterephthalate) exhibit improved impact properties over typical fillers for poly(butyleneterephthalate) resins. Impact properties can be further improved by the addition of a silane coupling agent to the poly(butyleneterephthalate) novaculite blend.
