Patent ID: 8748521

Claim:
A composition consisting 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, wherein the graft base is a silicone/acrylate composite rubber of mutually penetrating silicone rubber and polyalkyl (meth)acrylate rubber, wherein the content of silicone rubber is 65-95 wt. %, based on the graft base, and as a component B, a graft polymer of B.1 5 to 95 wt.% of at least one vinyl monomer 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 are mutually penetrating in the composite rubber, such that B.2.1 and B.2.2 cannot be separated substantially from each other, C) 4 to 12 parts by wt., in each case based on the sum of the parts by weight of components A+B+C+D, of talc having a d 98 value of less than 20 μm and having a d 50 value of from 0.2 to 2 μm, 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 flame retardant selected from the group consisting of mono- and oligomeric phosphoric and phosphonic acid esters, phosphonatamines and phosphazenes, and E) greater than 0 to 50 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 additive selected from the group consisting of flameproofing synergists, antidripping agents, lubricants and mould release agents, nucleating agents, stabilizers, acids, fillers and reinforcing substances which differ from talc, dyestuffs and pigments.
