阻滞苯乙烯阴离子聚合研究进展

Development of retarded anionic polymerization of styrene process

综述了近十年来阻滞阴离子聚合的研究进展,讨论了阻滞剂的种类、结构、用量对苯乙烯阴离子聚合活性的影响,闸述了阻滞剂的阻滞机理及阻滞阴离子聚合在高抗冲聚苯乙烯生产中的应用,寻找有效的引发剂体系生产高抗冲聚苯乙烯和研究工业化聚合工艺是今后的研究重点。

This paper reviewed the development of retarded anionic polymerization in the last decade, discussing the effect of kind, structure and content of retarders on the activity of styrene propagation and the retarding mechanism as well. In addition, the application of retarded anionic polymerization technique on the produc tion of high impact polystyrene was also introduced. The research focus in the future is seeking effective initiator systems for high impact polystyrene polymerization and studying industrialized polymerization processes.
