MINERAL-FILLED POLYCARBONATE BLEND MOULDING COMPOSITION HAVING A LOW BPA CONTENT, AND METHOD FOR PREPARING SAME
The invention relates to a thermoplastic moulding composition containing: A) at least one polycarbonate and/or polyester carbonate each containing structural units derived from bisphenol-A; B) a further polymer different from component A or a mixture consisting of polymers each different from component A, wherein Component B consists of B1) at least one thermoplastic polymer and optionally B2) at least one non-thermoplastic polymer; C) at least one inorganic filler selected from the group consisting of quartz compounds, talc, wollastonite, kaolin, CaCO.sub.3, titanium dioxide, and titanium dioxide in combination with other inorganic pigments, Al(OH).sub.3. AlO(OH), Mg(OH).sub.2 and mica as well as combinations of said fillers; and D) optionally at least one non-polymeric polymer additive and/or at least one non-polymeric processing aid, in each case different from component C, wherein the weight ratio of component B to component C is at least 0.5 and wherein the weight proportion of component B1 in component B is at least 20%, and wherein the moulding composition has a mass fraction of free bisphenol-A of less than 30 ppm. The invention also relates to: a method for producing a moulding composition; the use of the moulding composition to produce a moulded body; and a moulded body containing the moulding composition or consisting of the moulding composition.
