Boron- and nitrogen-containing compositions and their use in polycarbonate and polyester-polycarbonate synthesis |
摘要 |
Boron- and nitrogen-containing compositions prepared by the reaction of a quaternary ammonium hydroxide with a trialkyl or triaryl borate are useful for the preparation of the active catalyst species in the transesterification of reaction for the production of polycarbonates or polyester-polycarbonates from diaryl carbonates (optionally in admixture with diaryl dicarboxylates) and dihydroxyaromatic compounds.
