AI Technical Summary
Existing olefin polymerization catalysts face challenges in achieving high activity, molecular weight, and comonomer incorporation efficiency, particularly when copolymerizing olefins with polar group-containing vinyl monomers, and often require expensive activators like triphenylborane or tris(pentafluorophenyl)borane.
A monovalent anionic bidentate ligand with a specific alkylene structure and Group 15 or 16 elements as coordinating atoms, combined with nickel or palladium compounds, forms a catalyst with enhanced activity, molecular weight, and polar monomer incorporation efficiency.
The catalyst achieves high activity and efficient copolymerization of olefins with polar group-containing vinyl monomers, producing olefin polymers with improved properties without the need for expensive activators.
