    摘要： Continuous processes for preparing polycarbonates having a weight average molecular weight MW, of 15,000 to 200,000 g/mol, the processes comprising reacting a dihydroxydiarylalkane and phosgene in the presence of a catalyst in a phase boundary process comprising: continuously dispersing in a disperser an organic phase comprising at least a portion of the phosgene and a solvent suitable for the polycarbonate and an aqueous phase comprising the dihydroxydiarylalkane, water and an alkali solution present in an amount of 1.5 to 2.5 moles per mole of the dihydroxydiarylalkane, to form a mixture; reacting the mixture in a first reactor with a residence time of less than 0.5 seconds; further reacting the mixture in a second reactor with addition of further alkali solution and, optionally, a chain terminator; and effecting further condensation in a third reactor with addition of further alkali solution and, optionally, a chain terminator, in the presence of the catalyst.

    摘要： A thermoplastic composition having improved rheological and optical properties containing aromatic polycarbonate and an oligomeric epoxy resin is disclosed. The epoxy resin that conforms to formula (I) wherein R1, R2 mutually independently denote H, C1-C12 alkyl, cyclic C5-C12 alkyl, phenyl or benzyl groups and n is an integer of 0 to 20, contains no more than 0.1% water. A process for purifying the epoxy is also disclosed
