The invention relates to blends of special copolycarbonates and special polyetherimides or special polyarylsulfones which have good metallizability and to compositions of said copolycarbonate blends optionally containing additives which are selected from the group of thermo stabilizers and release agents, to the use thereof for producing molded parts and to molded parts produced therefrom. The invention further relates to multilayer products comprising a substrate which contains the compositions according to the invention, said products comprising at least one further layer, preferably a metal layer, on at least one side, and to methods for producing said products. |

1. A composition comprising
A) from 60% by weight to 99% by weight based on the sum of parts by weight of components A+B, of at least one copolycarbonate with a Vicat softening point of at least 160° C. comprising as chain terminator, terminal group, a structural unit of formula (1) in whichR1 comprises hydrogen or C1-C18-alkyl and
comprises at least one diphenol unit of formula (2), in whichR2C1-C4-alkyl,n 0, 1, 2, or 3, and B) from 1% by weight to 40% by weight based on the sum of parts by weight of components A+B, of at least one specific polyaryl sulfone and/or specific polyetherimide which have formula (I), (II), or (III) as repeating unit: in which A and B can be optionally substituted aromatic moieties, where the aromatic moieties comprising from 6 to 40 C atoms which comprise at least one optionally condensed aromatic nuclei, where the nuclei can optionally comprise at least one heteroatom, a such that the sum of the parts by weight of components A+B in the composition are 100. |
