合成间同立构PS用单中心催化剂的研究进展

Development of single-site catalysts for synthesis of syndiotactic polystyrene

综述了茂金属催化剂和非茂钛催化剂合成间同立构聚苯乙烯的研究进展,其中,茂金属催化剂主要包括茂钛催化剂、单茂钛催化剂、茚钛催化剂、双核金属催化剂及负载型催化剂等。今后的研究重点是负载型茂金属催化剂和非茂钛催化剂,单中心催化剂将对合成间同立构聚苯乙烯的工业化发展发挥重要的作用。

This paper reviewed the advances in studies on metallocene catalysts and non-titanocene catalysts for synthesis of syndiotactic polystyrene, focusing on five kinds of metallocene catalysts, i.e. titanocene catalyst, mono-titanocene catalyst, indene titanium catalyst, binuclear metal catalyst and supported catalyst. The supported metallocene catalyst and non-titanocene catalyst are deemed as the focus of research in the future. The single-site catalyst is supposed to play an important role in the industrial development of syndiotactic polystyrene.
