    摘要： A non-reactive monomer mixture is formed from a dihydroxy component having one or more dihydroxy compounds dissolved in a melted diaryl carbonate. The dihydroxy component has less than 600 ppb alkali metal, an acid stabilizer, or both less than 600 ppb alkali metal and an acid stabilizer. The dihydroxy compounds of the dihydroxy component and the diaryl carbonate are present in a mole ratio of from 0.9 to 1.1. The monomer mixture is at a temperature between the saturation point of the monomer mixture and the highest melting temperature of the individual dihydroxy compounds. The non-reactive monomer mixture can be stored and transported and then polymerized to form polycarbonate upon addition of a catalyst.

    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.
