    摘要: The present disclosure relates to impact-modified polycarbonate compositions which comprise a graft polymer containing silicone/acrylate composite rubber as the graft base, wherein the content of silicone rubber is 65-95 wt. % (based on the graft base), talc having a d98 value (also called “top cut”) of less than 20 μm and phosphorus-containing flame retardant, the use of the polycarbonate compositions for the production of shaped articles and the shaped articles themselves. The compositions and moulding compositions according to the disclosure have an optimum combination of good flameproofing, good resistance to chemicals and hydrolysis and good mechanical properties (i.e. in particular a high E modulus and high notched impact strength aK).
