Flame-resistant polyester molding compositions with polyolefin additives

A thermoplastic molding composition comprising:

• A) one or more polymeric resin selected from the group consisting of (co)polyester, polyestercarbonate and (co)polycarbonate,
• B) 10 to 40%, relative to the total weight of the composition, of a flame retardant component containing a nitrogen compound B.1) and a phosphorus compound B.2) of formula (I)
• 6
• where
• R1, R2, R3 and R4 each represent, independently of one another, C1 to C8 alkyl, C5 to C6 cycloalkyl, C6 to C20 aryl or C7 to C12 aralkyl,
• n independently one of the others is 0 or 1,
• m is 0 to 50 and
• X is a C6-30-aromatic radical with single or multiple rings,
• C) 0.05 to 1.5% relative to the total weight of the composition of polyolefin wax,
• D) 0 to 5% relative to the total weight of the composition of zinc sulphide,
• E) 0 to 50% relative to the total weight of the composition of one or more fillers and reinforcing agents and
• F) is 0 to 40% relative to the total weight of the composition of further additives,
• the sum of the weights of the components making up 100% by weight.
