Advances in polymer synthesis in microreactors

doi:10.3969/j.issn.0438-1157.2014.07.018

Abstract

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
