开发烯烃高活性、高选择性配位聚合催化剂在基础研究和工业应用领域都具有非常重要的意义,通过催化剂的设计实现聚烯烃在立构规整性上的精确控制,是高分子科学最重要的研究领域之一。中国科学院长春应用化学研究所高分子物理与化学国家重点实验室崔冬梅课题组一直致力于烯烃/共轭双烯烃高选择性聚合稀土催化剂的研究。在高性能橡胶的制备和功能化烯烃的高选择性聚合方面取得系列重要进展:(1)利用限制几何构型的吡啶茂基稀土催化剂实现了丁二烯、异戊二烯和苯乙烯的三元高选择性共聚合制备
It is of great significance to develop highly active and highly selective olefin polymerization catalysts for both basic and industrial applications. The precise control of the tacticity of polyolefins through the design of catalysts is of great importance to the polymer science One of the research areas. Cui Dongmei, State Key Laboratory of Polymer Physics and Chemistry, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences has been working on the highly selective rare earth catalysts for olefin / conjugated diene polymerization. A series of important advances have been made in the preparation of high performance rubber and in the highly selective polymerization of functionalized olefins: (1) Terpolymers of butadiene, isoprene and styrene have been achieved with pyridine-based rare earth catalysts with limited geometry Highly selective copolymerization
