titleOfInvention POLYMERIZATION DEVICE FOR OBTAINING AROMATIC POLYCARBONATES
abstract The object of the present invention is to provide a polymerization device and a system of polymerization devices that make it possible to obtain, by melt transesterification, high-quality aromatic polycarbonate with high performance properties (which is uncolored and has excellent mechanical properties) from a molten aromatic polycarbonate prepolymer, in turn obtained by the interaction of an aromatic polycarbonate dihydroxy compounds with diaryl carbonate, and the polycarbonate can be stably produced on an industrial scale from 1 to 50 t / h for a long time. In the present invention, the solution to this problem has been achieved with a down-flow polymerization device (in which the molten prepolymer is allowed to flow along the guide in contact with it, resulting in the polymerization of the prepolymer) having a specific design, as well as with the help of a polymerization system. devices including similar devices. Those. the specified device and system made it possible to stably obtain high-quality aromatic polycarbonate with high consumer properties, as indicated above, in an amount from 1 to 50 t / h for a long time (more than several thousand hours, for example 5000 hours), without fluctuations in the value of its molecular weight ...
