Abstract:
A catalyst for a polymerization of norbornene monomers includes a transition metal complex represented by a formula (1). A method for producing a norbornene copolymer includes copolymerizing first norbornene monomers corresponding to a first monomer unit represented by a formula (2) and second norbornene monomers corresponding to a second monomer unit represented by a formula (3) in a presence of the catalyst. The transition metal complex is preferably (π-allyl) {2-[N-(2,6-diisopropylphenyl) iminomethyl]phenolate}palladium, (π-allyl) {2-[N-(2,6-diisopropylphenyl)iminomethyl]-4-fluorophenolate}palladium, (π-allyl)[2-(N-phenyliminomethyl) phenolate]palladium or (π-allyl){2-[N-(2,6-diisopropylphenyl) iminomethyl]-6-methylphenolate}palladium.
