Abstract
A thermoplastic molding composition is disclosed. The composition that contains a polymer selected from the group consisting of a polycarbonate, a transparent polycarbonate-polyester-blend, a copolyestercarbonate and a transparent polyester and a compound of formula (I) and one or more compounds of formula (II) wherein a is 1 to 17, b is 0 to 16, c is 6 to 14, d is 3 to 7, e is 6 to 14, f is 3 to 7, g is 5 to 40 and a+b is 9 to 25 and n is 1 to 10, was found to be especially suitable for co-extrusion applications.
Claims11
A thermoplastic molding composition consisting essentially of polycarbonate and a compound of formula (I)
- and one or more different compounds of formula (II)
- wherein
- a is 1 to 17, b is 0 to 16, c is 6 to 14, d is 3 to 7,
- e is 6 to 14, f is 3 to 7, g is 5 to 40 and a+b is 17 and n is 1 to 10,
- and 0.1 to 15 percent by weight of a UV absorber, the percent being relative to the weight of the composition
- and optionally a thermal stabilizer in an amount of 10 to 3000 ppm relative to the total weight of the composition.
