Patent ID: 7186767

Claim:
A thermoplastic molding composition comprising A) 40 to 99.5 parts by weight of at least one branched resin selected from a first group consisting of aromatic polycarbonate and polyestercarbonate wherein the structure of the branched resin contains at least one residue of a branching agent selected from a second group consisting of tn-functional phenolic monomer and tetra-functional phenolic monomer, said agent containing at least one functional amine group capable of polymerization, B) 0.5 to 60 parts by weight of graft polymer containing a grafting shell and a grafting base, said grafting base being other than polybutadiene rubber, and C) at least one halogen-free, phosphorus-based flame-retardant comprising a compound according to formula wherein: R 1 , R 2 , R 3 and R 4 , independently of each other mean, in each case, C 1 to C 8 -alkyl, C 5 to C 6 -cycloalkyl, in each case optionally substituted by alkyl; each n, independently of each other, means 0 or 1; q is 0.5 to 30; each m, independently of each other, means 0, 1, 2. 3 or 4; R 5 and R 6 , independently of each other, are C 1 to C 4 -alkyl; and Y is C 1 to C 7 -alkylidene, C 1 –C 7 -alkylene, C 5 to C 12 -cycloalkylene, C 5 to C 12 -cycloalkylidene, —O—, —S—, —SO 2 —or —CO—.
