Abstract:
1. A composition comprising 40 to 95 parts by wt. of polycarbonate and/or polyester-carbonate, 1 to 35 parts by wt. of at least one impact modifier, 1 to 30 parts by wt. of at least one phosphorus-containing flameproofing agent selected from the group consisting of oligomeric phosphoric acid esters, phosphazenes and phosphonate-amines and 0.1 to 4 parts by wt. of a polyalkylene ether which is modified with at least one agent which forms free radicals and is based on propylene oxide and ethylene oxide, with a propylene oxide content, based on the polyalkylene ether, of at least 60 wt. %, the molding compositions are characterized in that they pass the UL94V test at a wall thickness of 1.6 mm with V-0 or V-1, said polyalkylene ether having the structure of a triple-block copolymer of the general formula X—Y—X, wherein X represents polyethylene oxide blocks and Y represents a polypropylpne oxide block.
