ABSTRACT:
A glass fiber reinforced thermoplastic molding composition suitable for the preparation of articles having good surface properties is disclosed. The composition contains a resinous blend and a filler component. The resinous blend contains (i) 20 to 50 wt. % of a grafted acrylate rubber, (ii) 2 to 10 wt. % of a first copolymer containing structural units derived from styrene (meth)acrylonitrile and maleic anhydride, (iii) 20 to 80 wt. % polyamide, and (iv) 0 to 40 wt. % of a second copolymer containing structural units derived from styrene and (meth)acrylonitrile, the percents being relative to the total amount of (i), (ii), (iii) and (iv). The filler component of the inventive composition contains 1 to 29 percent of milled glass fibers, in combination with 1 to 29 percent of chopped glass fibers, the percent being relative to the weight of the molding composition. Optionally, the inventive composition also contains a positive amount of a wollastonite. Molded articles that are prepared of the composition feature good mechanical properties and excellent surface quality.
