O'NX TITANIUM COMPLEXES-CATALYZED COPOLYMERIZATION OF ETHYLENE WITH FUNCTIONALIZED OLEFINS AND ITS APPLICATION AS A SUPPORTING MATERIAL IN CATALYTIC YLIDE REACTIONS

摘要

@@The copolymerization of ethylene with polar alkenes provides an easy and low-cost access to functional polyethytenes with unique properties. Two strategies including the use of late transition metal catalysts or masking the functional group of polar alkenes with Lewis acids have been developed. Even so, only very few catalysts exhibit high activity to afford polymers with good contents of polar comonomers.1,2
