    • This invention provides a method for preparing polycarbonates, which utilizes polycondensation catalysts which are derivatized pyridyl triazinyl pyridyl macromolecules with the general formula Ax+y[(Triazinyl-Pyridyl)By−x], where A is certain alkali metals, B contains a charge balancing sulfonate, carboxylate, or phosphonate group. We have found that this new class of catalysts provide excellent polymerization rates for the preparation of Bisphenol A polycarbonate from the melt polymerization of diphenyl carbonate and Bisphenol A. Moreover, the catalysts of the invention were found to be very selective in substantially reducing the level of branching side reaction, i.e., formation of Fries product, normally associated with the melt polycarbonate process.
    • 本发明提供一种制备聚碳酸酯的方法,该方法采用衍生化的具有通式Ax + y [(三嗪基 - 吡啶基)By-x]的吡啶基三嗪基吡啶基大分子的缩聚催化剂,其中A是某些碱金属,B含有电荷平衡 磺酸盐,羧酸盐或膦酸盐基团。 我们已经发现,这种新类型的催化剂从碳酸二苯酯和双酚A的熔融聚合制备双酚A聚碳酸酯提供了极好的聚合速率。此外,发现本发明的催化剂在显着降低 分支侧反应,即通常与熔融聚碳酸酯方法相关的Fries产物的形成。

    • In an exemplary embodiment, the apparatus includes an electromagnetic radiation source, an optical analyzer, and a fiber optic bundle. The fiber optic bundle has an excitation fiber in optical communication with the electromagnetic radiation source and a plurality of emission fibers in optical communication with the optical analyzer. The optical analyzer can have multiple channels, including a fluorescence-emission channel in optical communication with the emission fibers. Optionally, the fiber optic bundle can further contain at least one reflection fiber in optical communication with an absorbance/reflectance channel. In addition to detecting Fries product in formed polycarbonate materials, the method and apparatus can also be utilized to directly determine the concentration of a target species in parallel polycarbonate reactor systems.
    • 在示例性实施例中,该装置包括电磁辐射源,光学分析器和光纤束。 光纤束具有与电磁辐射源光通信的激励光纤和与光学分析器光学通信的多个发射光纤。 光学分析仪可以具有多个通道,包括与发射光纤光学通信的荧光发射通道。 可选地,光纤束还可以包含与吸光度/反射率通道光连通的至少一个反射光纤。 除了在形成的聚碳酸酯材料中检测Fries产品之外,还可以使用该方法和装置来直接确定并联聚碳酸酯反应器系统中靶物种的浓度。
