摘要： A method of preparing a high molecular weight polycarbonate resin is provided. In the method, a condensation polymerization process is used so that a mole fraction of arylcarbonate existing in a terminated group of a reaction side product having a degree of polymerization of less than 3 obtained as a result of transesterification and in a non-reacted diarylcarbonate is reduced. As a result, a high molecular weight polycarbonate can be obtained by solid state polymerization. A polycarbonate with an identical molecular weight can be produced in a substantially short time, compared with a polycarbonate produced through solid state polymerization without condensation polymerization. In addition, the non-use of a poisonous phosgene contributes to stability. Furthermore, quality polycarbonate may be guaranteed.
摘要翻译：提供了制备高分子量聚碳酸酯树脂的方法。在该方法中，使用缩聚方法，使得存在于作为酯交换反应的结果得到的聚合度小于3的反应副产物的末端基团中的芳基碳酸酯的摩尔分数和未反应的碳酸二芳基酯的摩尔分数为减少结果，可以通过固态聚合获得高分子量聚碳酸酯。与通过不进行缩聚的固相聚合制造的聚碳酸酯相比，可以在短时间内生产具有相同分子量的聚碳酸酯。此外，不使用有毒光气有助于稳定。此外，可以保证质量的聚碳酸酯。

摘要： Provided is a method of producing a high-molecular weight modified polycarbonate resin. The method includes a melt condensation polymerization process in which transesterification and quick condensation polymerization are sequentially performed, a spray crystallization process, and a solid state polymerization process. When this method is used, solid state polymerization can be performed without additional drying, milling and fractionation processes so that the operation time and costs are highly reduced. In addition, crystallinity and size of crystallized modified polycarbonate particles can be efficiently controlled to produce a high-molecular weight modified polycarbonate having uniform physical properties in the solid state polymerization.
摘要翻译：提供高分子量改性聚碳酸酯树脂的制造方法。该方法包括依次进行酯交换和快速缩聚的熔融缩聚方法，喷雾结晶法和固态聚合法。当使用该方法时，可以进行固态聚合而不需要额外的干燥，研磨和分馏过程，从而高度降低操作时间和成本。此外，可以有效地控制结晶化聚碳酸酯颗粒的结晶度和尺寸，以制备在固态聚合中具有均匀物理性能的高分子量改性聚碳酸酯。
