摘要

The present invention relates to the transesterification of the carbonic acid aryl esters obtainable according to German Published Patent Specification No. 2,650,533 with an excess of diphenol for the preparation of polyalkylene oxide-diol bis-diphenol carbonates lengthened via carbonate groups. The present invention also relates to the polyalkylene oxide-diol bis-diphenol carbonates, lengthened via carbonate groups, obtained according to the invention and their use for the preparation of polyether/polycarbonates. Finally, the present invention relates to the polyether/polycarbonates, obtained according to the invention, with an improved phase separation between the elastomeric segment and hard segment, which leads to better technological properties of the corresponding polycarbonate elastomers.
