Dipalladium Catalyst for Olefin Polymerization: Introduction of Acrylate Units into the Main Chain of Branched Polyethylene


  • This work was supported by a Grant-in-Aid for Young Scientist No. 22685012 for Scientific Research from the Ministry of Education, Science, Sports and Culture (Japan).


A dipalladium complex with a double-decker structure catalyzes ethylene–acrylate copolymerization to produce the branched polymer containing the acrylate units in the polymer chain, not at the branch terminus. The cooperation of the two palladium centers, which are fixed in a rigid framework of the macrocyclic ligand, is proposed to have a significant dinuclear effect on the copolymerization.
