| titleOfInvention | Method for producing a polycarbonate moulding compound |
| abstract | The present invention relates to a method for producing a thermoplastic moulding compound containing A) at least one aromatic polycarbonate and B) an additional polymer that is chemically different from polymer A and that contains at least one type of functional group selected from ester groups, epoxy groups, hydroxyl groups, carboxyl groups and carboxylic anhydride groups, comprising the steps of a) melting and thoroughly mixing the components A and B in the presence of a catalyst according to component Cat a temperature in the range of from 200° C. to 350° C. and b) solidifying the composition by cooling the composition, the component A having an average molecular weight Mw of at least 3000 g/mol, characterised in that, in the method step a), at least one part of the component A is reacted with the component B to form a copolymer, and the catalyst C being a specific phosphonium salt. The invention also relates to a thermoplastic moulding compound produced by the method according to the invention, and to moulded bodies containing said moulding compound. |
