The present invention relates to filled, impact resistant-modified polycarbonate compositions, comprising: A) aromatic polycarbonate and/or aromatic polyester carbonate, B) a first graft polymer of B.1 0.1 to 30% by weight of at least one vinyl monomer on B.2 99.9 to 70% by weight of one or more graft bases having glass transition temperatures of < 10°C, wherein the graft base is made at least 50% by weight of a silicon rubber, C) a second graft polymer, which differs from component B, of C.1 5 to 95% by weight of at least one vinyl monomer on C.2 95 to 5% by weight of one or more graft bases having glass transition temperatures of < 10°C, wherein the graft base is made at least 50% by weight of an EPDM rubber, D) rubber-free vinyl(co)polymer and/or polyalkylene terephthalate, and E) polymer additives, wherein components B and C are present in a ratio (B:C) in the range from 20:80 to 80:20, and wherein the composition comprises 10 to 92 parts by weight of component A, 8 to 90 parts by weight of the sum of components B and C, 0 to 35 parts by weight of component D, and 0 to 30 parts by weight of component E. The compositions exhibit good resistance to aging and are characterized by high low-temperature stability and by low glossiness. The invention further relates to a method for the production of the compositions, and their use for producing molded bodies.
