摘要
The invention relates to a composition for producing a thermoplastic molding compound, wherein the composition contains or consists of the following constituents, A) 30 to 90 wt% of at least one polymer selected from the group consisting of aromatic polycarbonate, aromatic polyester carbonate and aromatic polyester, B) 5 to 65 wt% of polymer free of epoxide groups, consisting of B.1) rubber-modified vinyl (co)polymerizate produced in the emulsion polymerization process and B.2) optionally rubber-free vinyl (co)polymerizate, C) 0.5 to 10 wt% of a block polymer or graft polymer containing structural elements originating from styrene and from at least one epoxide-group-containing vinyl monomer, D) 0.001 to 20 wt% of one or more further additives, wherein component C has a weight ratio of structural elements originating from styrene to structural elements originating from epoxide-group-containing vinyl monomer of 100:1 to 1:1, and wherein at least one of the constituents of the composition contains a Brønsted-acidic and/or Brønsted-basic compound. The invention relates to a method for producing a molding compound from the composition, to the molding compound itself, to the use of the composition or the molding compound to produce molded bodies, and to the molded bodies themselves.
