主　　题：Dual-regulated Stimulus-responsive Palladium Ethylene polymerization Polar monomer 

摘      要：The external stimulus response strategy has been evolved rapidly in the field of olefin *** this work,we modularly synthesized three types of double stimulus responsiveα-diimine palladium catalysts,combining redox regulation and other regulation together,such as light,Lewis acid and alkali *** catalytic activities and the molecular weight of polyethylene products can be regulated for 4 times in ethylene *** palladium complexes were also used for the copolymerization reaction of ethylene and polar monomers,such as methyl 10-undecylenate and methyl acrylate,effectively regulating the catalytic activities,the molecular weight and polar monomer incorporation of the prepared *** research on these dual-regulated palladium complexes makes full use of prepared catalysts and provides new inspirations for regulating olefin polymerization.
