FIELD: chemistry.
SUBSTANCE: invention relates to thermoplastic polycarbonate moulding compositions for production of various moulded articles. The composition contains an aromatic polycarbonate and/or polyestercarbonate or a rubber-modified graft copolymer with content of lithium impurities of 0.8-8 parts per million. The copolymer is obtained via mass, solution or block-suspension polymerisation.
EFFECT: invention enables to obtain a composition with low content of lithium ions and higher resistance to hydrolysis.
