Title: Polyolefin Catalyst: Design, Modulation and Application
Abstract:
In the past 50 years, the studies of olefin polymerization have achieved great successes in both academia and industry. Polyolefins have huge annual production and wide applications. However, one of their biggest limitations is their nonpolar nature. The introduction of a small amount of polar functionalized groups can greatly improve many properties, broaden their applications and increase their business values. Transition metal catalyzed copolymerizations of olefin with polar monomers is the most direct route to access polar functionalized polyolefins, which is also highly challenging. With the “polar monomer problem” as the central theme, this account mainly focuses the works from our research group and describes the following topics: modification of existing catalyst systems, development of new catalyst systems, design of new polymerization modulation strategies, and the synthesis and property studies of special polyolefins and polar functionalized polyolefins materials.
