Abstract
Polymers comprising polycyclic repeating units containing pendant anhydride moieties are disclosed. The polymer can be polymerized from polycycloolefins containing pendant anhydride moieties in the presence of a nickel containing single component catalyst. In optional embodiments the polycycloolefin monomer containing the pendant anhydride functionality can be copolymerized with other polycycloolefin monomers that contain pendant functional groups to yield random copolymer products.
