摘要:
The present invention relates to a process for the preparation of aromatic polycarbonates, aromatic polyester carbonates and aromatic polyesters by the known two phase interface process, which is characterized in that the organic phase used is a mixture of aromatic hydrocarbons with alkanes and/or cycloalkanes.
