摘要

Introduction of polar comonomers into polyethylene is highly challenging,paving the way to tuning the copolymers' mechanical properties,adhesion/compatibility,and biodegradability.Polar-group tolerant single-site palladium and,more tempting,nickel-based catalysts have demonstrated promising reactivities in the ethylene copolymerization with polar comonomers via coordination/insertion mechanism,providing tighter control of polymer microstructures and requiring milder reaction conditions compared with radical-initiated processes;in the last decade,the respective areas have advanced a lot [1,2].
