摘要:
The invention relates to a process for the production of aromatic polycarbonates, aromatic polyester carbonates and aromatic polyesters by the known two-phase interfacial method which is characterized in that a mixture of aromatic hydrocarbons with alkanes and/or cycloalkanes is used as the organic phase and in that phosphines or phosphine oxides are used as the catalysts.
