Patent ID: 8178603

Claim:
A composition consisting essentially of A) 40 to 99 parts by wt., in each case based on the sum of the parts by weight of components A+B+C+D, of aromatic polycarbonate and/or aromatic polyester carbonate, B) 0.5 to 20 parts by wt., in each case based on the sum of the parts by weight of components A+B+C+D, of graft polymer, consisting of B.1 5 to 95 wt. % of one or more vinyl monomers on B.2 95 to 5 wt. % of one or more silicone/acrylate composite rubbers as the graft base, wherein the silicone/acrylate rubber comprises B.2.1 65-95 wt. % of silicone rubber and B.2.2 35 to 5 wt. % of polyalkyl(meth)acrylate rubber, wherein the two rubber components B.2.1 and B.2.2 mentioned are mutually penetrating in the composite rubber, wherein B.2.1 and B.2.2 cannot be separated substantially from one another, C) 0.1 to 20 parts by wt., in each case based on the sum of the parts by weight of components A+B+C+D, of graft polymer, consisting of C.1 5 to 95 wt. % of at least one vinyl monomer on C.2 95 to 5 wt. % of at least one graft base containing diene rubber, and the graft polymer has a core-shell structure prepared in the emulsion polymerization process, which has a graft base C.2 with an average particle size (d 50 value) of from 0.15 to 0.4 μm, and D) 0.4 to 20 parts by wt., in each case based on the sum of the parts by weight of components A+B+C+D, of at least one flameproofing agent selected from the group consisting of mono- and oligomeric phosphoric and phosphonic acid esters, phosphonatamines and phosphazenes.
