催化剂催化二氧化硫共聚的研究进展

Progress in Catalyst Catalyzed Sulfur Dioxide Copolymerization

目前有关二氧化硫(SO2)减排技术的研究成熟且较多,而SO2的高效利用却研究较少。SO2与烯烃、环氧化物及其他单体共聚制备含硫高分子是利用SO2的有效途径。探索和开发新型高效催化剂是提高其共聚反应效率及调控共聚物结构的根本手段和方法,因此,高效催化剂成为该领域的研究重点。文中分析比较了有机金属、过氧化物、Lewis酸、Lewis碱等催化剂对SO2与单体共聚制备含硫高分子的影响规律,希望对SO2催化共聚的研究和发展提供参考。

The emission reduction technology of sulfur dioxide(SO2)was researched well,compared with the efficient utilization of SO2.Copolymerization of SO2 with olefins,epoxides and other monomers to prepare sulfur-containing polymers is an effective way to utilize SO2.Exploring and developing new high-efficiency catalysts is the fundamental means and method to improve the copolymerization reaction efficiency and regulate the structure of copolymers,therefore,high-efficiency catalysts have become the focus of research in this field.In this paper,the effects of organometallic,peroxide,Lewis acid,Lewis base and other catalysts on the preparation of sulfur-containing polymers by SO2 and monomer copolymerization were analyzed and compared.It is hoped to provide guidance for the research and development of SO2 catalytic copolymerization.
