摘　　要：2019年国际纯粹与应用化学联合会(IUPAC)纪念成立100周年,首次推出的化学领域十大新兴技术,反应挤出技术是其中之一。反应挤出是实现完全无溶剂化的绿色反应过程强化技术,尤其在天然物质改性、加工方面得到越来越广泛的使用。近年来国际上大力发展和推广反应挤出新技术,以消除使用溶剂带来的环境和安全问题。本文对近期反应挤出的发展与应用进行了综述,尤其是在天然高分子改性与加工方面。首先简单回顾了反应挤出的发展,然后着重介绍近年来在理论和技术上的最新进展,以高黏度天然高分子淀粉为例,详细介绍从设备设计改造及工艺到多引发体系设计和机理研究的突破。最后指出这项技术的不足之处和研究的方向。Reactive extrusion has been recognized as one of the top 10 emerging technologies in chemistry in the first time by the International Union of Pure and Applied Chemistry(IUPAC) during its 100th anniversary in 2019. Reactive extrusion is a green reaction process strengthening the technology that can be completely solvation free, especially in the modification and processing of natural substances. In recent years, the various new reactive extrusion technologies have been developed and popularized internationally to eliminate the environmental and safety problems caused by the use of solvents. In this paper, the recent development and application of reactive extrusion are reviewed, especially in the modification and processing of natural polymers. Firstly, the development of reactive extrusion is briefly reviewed, and then the latest progress in theory and technology in recent years is introduced. Taking high viscosity natural polymer starch as an example, the breakthroughs from equipment design, modification and process to multi-initiator system design and mechanism research are introduced in detail. Finally, the shortcomings and research directions of this technology are discussed.
