    摘要： A surface of a melt polymerization reactor system having residual reaction components of a melt polymerization reaction thereon can be cleaned by introducing a cleaning agent having a phenolic compound to the polymerization reactor system and into contact with the surface of the melt polymerization reactor system having the residual reaction components of a melt polymerization reaction thereon. The residual reaction components of the melt polymerization reaction include polycarbonate oligomers or polymers or their degradation products. Further, the cleaning agent is maintained in contact with the surface for a period of time and at a temperature sufficient to substantially remove the residual reaction components from the surface.

    摘要： The present invention provides methods of producing high molecular weight polymer. A method of forming polycarbonate includes the step of combining in a reaction mixture a diaryl carbonate, a transesterification catalyst, an aliphatic dihydroxy compound, and a diacid compound in a reactor system. The temperature and pressure of the reactor system are adjusted to a first reactor setpoints and the reaction mixture is monitored to detect initiation of the exothermic oligomerization reaction. The reactor setpoint are adjusted to second reactor setpoints after detection of initiation of the exothermic oligomerization reaction. The reactor system is maintained at the second reactor setpoints to allow the reaction mixture to react to form an oligomer mixture. The oligomer mixture is then introduced to a polymerization reactor system operating under melt polymerization conditions sufficient to polymerize the oligomer mixture to a Mw of at least 9,000 g/mol (PC) and to remove the phenolic byproduct from the oligomer mixture to form polycarbonate.

    摘要： A method of making a polycarbonate is described. The method comprises melt reacting an ester-substituted diaryl carbonate and a multifunctional compound of the formula: in the presence of catalyst to form an oligomer comprising less than 2,000 ppm of an ester-linked terminal group, and melt polymerizing the oligomer to form a polycarbonate. Use of specific reaction conditions produces a polycarbonate having an Mw of greater than or equal to 25,000 g/mol as determined by gel-permeation chromatography relative to polystyrene standards. Polycarbonates comprising units derived from the multifunctional compound, including homopolycarbonates, aliphatic copolycarbonates further comprising units derived from an aromatic dihydroxy compound, and aliphatic polycarbonate-polyesters, are also disclosed, as are a thermoplastic composition and an article including the disclosed polycarbonates.

    摘要： A polycarbonate is provided that contains repeat units derived from isosorbide and a residue derived from an activated diaryl carbonate. The polycarbonate has 1H-NMR peaks associated with the repeat units derived from isosorbide. The polycarbonate contains no more than a maximum allowable amount of sorbitol-derived color bodies. If these color bodies are present in the polycarbonate it has a 1H-NMR peak associated with the color bodies. The maximum allowable amount of color bodies are present when the integrated area of the 1H-NMR peak associated with the color bodies divided by the integrated areas of the 1H-NMR peaks associated with the repeat units derived from isosorbide is 0.025.
