摘　　要：聚合反应器为PC生产过程中的核心设备,尤其对于终缩聚过程,需要在高温、高真空度下进行,其内构件设计不仅要考虑高黏聚合体系的混合与传热,而且需要考虑副产物苯酚的高效脱除。本文综述了终缩聚反应器结构的研究进展,并对该反应器的应用研究进行了展望。The polymerization reactor is the core equipment in the PC production process,especially for the final polycondensation process,which needs to be carried out under high temperature and high vacuum conditions.The design of its internal components not only needs to consider the mixing and heat transfer of the high viscosity polymerization system,but also needs to consider the efficient removal of by-product phenol.This article reviews the research progress on the structure of final polymerization reactors and provides prospects for the application research of this reactor.
