The present invention relates to halogen-free flameproof thermoplasticnmolding compounds which comprise an aromatic polycarbonate, a styrene-containingncopolymer, a styrene-containing graft polymer, a phosphorusncompound, a silicon compound, and a tetrafluoroethylene polymer. It hasnbeen found that the use of a specific type of silicon compound leads to anpolymer mixture having improved stress crack resistance and impact properties. n The silicon compound is represented as the following General Formulan(1). n General Formula ( I ):n n in which n and m have a value of from 5 to 8, and x and y have a valuenof from 1 to 5. |
