Incorporation of small amounts of polar functional groups into non-polar polyolefins can dramatically improve properties of polyolefins. The development of late transition metal complexes for olefin copolymerization with polar monomers according to different types of complexes in the last decade is reviewed. With regard to α-diimine, phosphino-phenolate, salicylaldimine, ketoamine, phosphine-sulfonate, bisphospnine monoxide, N-heterocyclic carbene complexes and more emerging catalysts, fine modulation of key copolymerization parameters (activity, molecular weight, polar monemer incorporation, etc.) and material properties of polyolefins in a controlled way are described in detail. Despite many recent advances and enticing characteristics of these catalysts, there still remains challenges for industrial and commercial application due to a variety of limitations. To overcome some of these challenges, a brief outlook on the future of issues should be focused on is provided.
Key words: catalyst, polymerization, complex, olefin, polar monomer, late transition metal
