Also provided are neutral or cationic coordination complex dimers, so that the two palladium atoms are both bonded to one or two donor atoms from group 16, and each palladium atom is bonded to two donor atoms from group 15. In some instances, each of the two group 16 donor atoms are oxygen and each of the four group 15 donor atoms are nitrogen.

  • Patent number: 8785574
    Abstract: According to the invention, a single or plural kinds of bridged metallocene compounds having differing cyclopentadienyl-derived groups afford macromonomers that are a source of long-chain branches and simultaneously catalyze the repolymerization of the macromonomers into olefin polymers having a large number of long-chain branches, small neck-in in the T-die extrusion, small take-up surge and superior mechanical strength. The olefin polymerization catalysts and the polymerization processes can efficiently produce the olefin polymers.
