More Information
Summary:Compositions comprising: A) 50 to 95 parts by weight of at least one polymer selected from the group consisting of aromatic polycarbonate and aromatic polyestercarbonate, B) 5 to 50 parts by weight of at least one branched polyester, the polyester being derived from succinic acid and optionally further dicarboxylic acids and aliphatic, cycloaliphatic or araliphatic diols, C) 0 to 20 parts by weight of graft polymer, D) 0 to 20 parts by weight of vinyl (co)polymer and/or polyalkylene terephthalate, E) 0.0 to 30 parts by weight of additives, the parts by weight being standardized to the total weight of the composition, and also the use of these hydrolysis-stable polycarbonate/polyester compositions for producing shaped bodies, and the shaped bodies themselves, where the polyester in the composition can be obtained or prepared preferably from renewable raw materials.
