Patent ID: 7868070

Claim:
A thermoplastic molding composition comprising A) an aromatic polycarbonate and/or polyester carbonate in an amount of 30 to 99.9 pbw, B) an impact modifier in an amount of 1 to 40 pbw, wherein component B comprises a rubber-modified graft polymer of B.1) 5 to 95 percent based on the weight of B), of the polymerized product of a mixture including B.1.1) 50 to 99 percent, based on the weight of B.1), of at least one monomer selected from the group consisting of vinylaromatics, nucleus-substituted vinyl aromatics and (meth)acrylic acid (C1-C8)-alkyl esters and B.1.2) 1 to 50 percent based on the weight of B.1), of at least one monomer selected from the group consisting of vinyl cyanides, (meth)acrylic acid (C1-C8)-alkylesters and derivatives of unsaturated carboxylic acids grafted on B.2) 95 to 5 percent based on the weight of B), of one or more graft bases having a glass transition temperature lower than −10° C., C) a thermoplastic homo- and/or copolymer in an amount of 0 to 30 pbw, D) a modified layered compound in an amount of 0.1 to 40 pbw, the modification with organic polymer by means of a solvent-free melt process, wherein said organic polymer is polyalkylene oxide or a mixture of polyalkylene oxides having a number-average molecular weight of 106 to 20,000 g/mol, and E) a phosphorus compound in an amount of 1 to 20 pbw, conforming to formula (IV) wherein R 1 , R 2 , R 3 , and R 4 independently of one another denote C 1 to C 8 -alkyl, C 5 to C 6 -cycloalkyl, C 6 to C 20 -aryl or C 7 to C 12 -aralkyl, in each case optionally halogenated or alkyl substituted, n independently of one another, denotes 0 or 1, q denotes 0 to 30 and X denotes a mono- or polynuclear aromatic radical having 6 to 30 C atoms or a linear or branched aliphatic radical having 2 to 30 C atoms, which may be OH-substituted and may contain up to 8 ether bonds, and, wherein the sum of the parts by weight of components A, B, C, D and E is 100.
