Stereoselective Copolymerization of Olefin with Polar Monomers to Access Stereoregular Functionalized Polyolefins

Introducing polar functionalities to polyolefins such as polyethylene and polypropylene is highly desirable for improving physical properties of the otherwise non-polar material. The synthesis stereoregular functionalized polyolefins, however, has been a relatively underdeveloped area compared that because lack suitable catalysts tolerate groups while possessing stereoselectivity. This review summarizes recent advances concerning access including synthetic strategies post-functionalization, chain transfer direct copolymerization methods. focus lies in approach, which various comonomers versatile stereoselective polymerization based on both early late transition metals are involved.
