摘要: 微反应器作为化学工程学科的前沿和热点方向,逐渐成为聚合物合成的新装备、新工艺与新产品开发的重要平台,得到学术界和产业界的广泛关注。微反应器可实现可控的多相微尺度流动,能够强化聚合反应中的混合、传质和传热过程,严格控制反应时间,实现反应单元的模块化组合。与传统搅拌反应器相比,这些特点使得微反应器在控制聚合物分子量分布,简化反应环境,提高反应选择性,调节聚合物分子结构和宏观形貌等方面展现出了一定优势。本文全面综述了聚合物合成微反应器理论和技术的研究进展,并在新过程和新产品开发、反应动力学测量、微尺度基础研究和反应器放大等方面进行了展望。

Abstract: Microreactor is a frontier and hot topic in the research of chemical engineering. It is an important platform of polymer synthesis in the development of new equipment, new technology, and new product, drawing attentions from academia and industry. Microreactors make possible well-controlled multi-phase flow, intensified mixing and mass/heat transport process, strictly-controlled reaction time, and modularized configuration in polymerization reactions. Comparing with the common batch reactors, some advantages of microreactors are producing polymeric materials with narrow molecular weight distribution, adjustable molecular architecture, or controlled macroscopic structure. In this review, the theoretical and technological advances in polymer synthesis using microreactors are introduced. Some further research issues are also discussed, including developing new polymerization process and new polymer product, measuring reaction kinetics, exploring chemical engineering fundamentals at micrometer scale, and scaling up the microreactor.

Key words: microreactor, polymerization reaction, molecular weight distribution, polymers
