具有双层结构的二钯络合物催化乙烯-丙烯酸酯共聚以产生在聚合物链中而不是在分支末端含有丙烯酸酯单元的支化聚合物。两个钯中心的合作，这是固定在一个刚性的大环配体的框架，提出了具有显着的双核效应的共聚。
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.
