    Abstract: A thermoplastic molding composition comprising A) at least one member selected from the group consisting of polycarbonate and polyestercarbonate and B) a phosphorus compound is disclosed. The composition wherein A) is a mixture of (A.1) 99.9 to 40 wt. % of branched member, and (A.2) 0.1 to 60 wt. % of linear member, is characterized by high melt stability and improved mechanical properties, particularly improved stress crack resistance under the effect of chemicals and a higher notched impact resistance. The composition is especially suitable for producing profiles, films or sheets of any type in an extrusion process.

    Abstract: The invention relates to a composition that contains: A) 50 to 90 parts by weight of a polycarbonate and/or polyestercarbonate, b) 5 to 20 parts by weight of rubber-modified vinyl(co)polymers, C) 2 to 15 parts by weight of a t least one not easily volatized halogen-free flame retardant, D) 0.1 to 6 par ts by weight of a silicate mineral, E) 0 to 1 parts by weight of fluorinated polyolefin, and F) 0 to 10 parts by weight of polymer additives. The composition has a rubber content, based on the total composition, of at leas t 2 and of not more than 6 % by weight and the sum of parts by weight of A) to F) totals 100. The invention also relates to the shaped parts that are produced from the inventive composition.
