  • Olefin polymerization process
    Patent number: 6103920
    Abstract: Disclosed herein is a process for the polymerization of ethylene, norbornenes and styrenes, by contacting in solution a selected nickel compound and a selected compound which is or can coordinated to the nickel with the olefin(s). The polymers produced are useful for films and molding resins.
