Patent ID: 7223812

Claim:
A thermoplastic molding composition consisting of: (A) at least one member selected from the group consisting of aromatic polycarbonate and polyester-carbonate; (B) at least one graft polymer of, (B.1) 5 to 95% relative to the weight of the graft polymer of a graft shell that includes the polymerized mixture of, (B.1.1) 50 to 99 parts by weight of at least one member selected from the group consisting of vinylaromatic monomer, nucleus-substituted vinylaromatic monomer and (C 1 –C 8 )-alkyl ester of methacrylic acid, and (B.1.2) 1 to 50 parts by weight of at least one member selected from the group consisting of vinyl cyanide, (C 1 –C 8 )-alkyl ester of (meth)acrylic acid, anhydrides of unsaturated carboxylic acids and imides of unsaturated carboxylic acids, the total of the parts by weights being 100, and (B.2) 95 to 5% relative to the weight of the graft polymer of a graft base that contains a rubber having a glass transition temperature of below about 10° C., said graft base having a median particle size of 0.2 to 1 μm; (C) talc having median particle diameter of less than 600 nm; (D) at least one member selected from the group consisting of rubber-free vinyl (co)polymer and polyalkylene terephthalate; (E) a phosphorous-containing compound represented by the following formula wherein R 1 , R 2 , R 3 and R 4 , independently of each other, denote a member selected from the group consisting of C 1 to C 8 -alkyl, C 5 to C 6 -cycloalkyl, C 6 to C 20 -aryl and C 7 to C 12 -aralkyl, each n independently of each other, denotes 0 or 1, q denotes 0 to 30, and X denotes a mono- or polynuclear aromatic radical having 6 to 30 carbon atoms or a linear or branched aliphatic radical having 2 to 30 carbon atoms; (F) optionally an anti-dripping agent selected from the group consisting of fluorinated polyolefins and aramids; and (G) optionally at least one member selected from the group consisting of nucleating agents, antistatics, stabilizers, fillers, reinforcing substances, dyestuffs, pigments, pentaerythritol tetrastearate and further flame proofing agents, said further flame proofing agents being selected from the group consisting of decabromobisphenyl ether, tetrabromobisphenol, ammonium bromide, melamine, melamine-formaldehyde resins, Mg hydroxide, Al hydroxide, antimony oxides, barium metaborate, hydroxoantimonate, zirconium oxide, zirconium hydroxide, molybdenum oxide, ammonium molybdate, zinc borate, ammonium borate, barium metaborate, silicate, silicon oxide, tin oxide and combinations thereof.
