Paragraph 0033, (2017/02/24)
PROBLEM TO BE SOLVED: To provide a method for industrially advantageously produce a bisphenol derivative having a cyclic hydrocarbon in which a cyclic ketone has a 7- or more membered ring without using a hydrogen chloride gas having a strong corrosivenes
Design and synthesis of new polymeric materials for organic nonvolatile electrical bistable storage devices: Poly(biphenylmethylene)s

The synthesis of new polymers, poly(biphenylmethylene)s, derived from bistriflates of bisphenol-type monomers, by Ni(0)-mediated polymerization has been presented. These polymers are interesting because of the nature of the polymer backbone that contains
Method for preparing aromatic bischloroformate compositions
-
, (2008/06/13)
Bischloroformate oligomer compositions are prepared by passing phosgene into a heterogeneous aqueous-organic mixture containing at least one dihydroxyaromatic compound, with simultaneous introduction of a base at a rate to maintain a specific pH range and to produce a specific volume ratio of aqueous to organic phase. By this method, it is possible to employ a minimum amount of phosgene. The reaction may be conducted batchwise or continuously. The bischloroformate composition may be employed for the preparation of cyclic polycarbonate oligomers or linear polycarbonate, and linear polycarbonate formation may be integrated with bischloroformate composition formation in a batch or continuous process.
