摘要： This invention relates to an extrusion method preparing polycarbonates from a solution of an oligomeric polycarbonate. A mixture of bis(methyl salicyl) carbonate (BMSC), BPA and a transesterification catalyst are first equilibrated at moderate temperatures to provide a solution of polycarbonate oligomer in methyl salicylate. The solution is then fed to a devolatilizing extruder, where the polymerization reaction is completed and the methyl salicylate solvent is removed. The solution comprising the oligomeric polycarbonate can also be pre-heated under pressure to a temperature above the boiling point of methyl salicylate and subsequently fed to a devolatilizing extruder equipped for rapid flashing off the solvent. The method provides polycarbonate with greater efficiency than the corresponding process in which unreacted monomers are fed to the extruder. Additionally, the method of the invention does not require the isolation of a precursor polycarbonate comprising estersubstituted phenoxy terminal groups.

摘要： The invention provides novel copolycarbonates that exhibit improvements in glass transition temperature, refractive index, and limiting oxygen index compared to prior art thiodiphenol/bisphenol A copolycarbonates. The copolycarbonates of this invention comprise the reaction products of 4,4'-thiodiphenol and compounds such as 9,9-bis (4-hydroxyphenyl) fluorene with phosgene. They are useful as components of multilayered polymeric reflective bodies.

摘要： The present invention provides: a new synthetic resin laminated sheet in which whitening, cracking, and foaming do not occur when thermoforming is carried out, in particular when deep-draw molding is carried out, and in which defects similarly do not occur during lamination of a hard coating layer; and a molded article obtained by molding said laminated sheet. Provided is a synthetic resin laminated sheet which has a coating layer, which is configured to include an acrylic resin (B), laminated on one surface of a substrate layer comprising a polycarbonate resin (A) in which a monohydric phenol represented by general formula (1) is used as a chain terminator and which is obtained by reacting said monohydric phenol with a dihydric phenol and a carbonate binding agent and has a viscosity average molecular weight of 18000-35000. (In the formula, R1 represents a C8-36 alkyl group or a C8-36 alkenyl group. R2-R5 each represent hydrogen, halogen, or an optionally substituted C1-20 alkyl group or C6-12 aryl group).
