Patent ID: 7268196

Claim:
A process for producing a cycloolefin addition polymer, comprising addition-polymerizing one or more cycloolefin monomers comprising a cycloolefin compound represented by formula (1) in the presence of a multi-component catalyst, comprising: (a) a palladium compound, and (b-2) an addition complex of a phosphine compound that comprises a substituent selected from the group consisting of an alkyl group of 3 to 15 carbon atoms, a cycloalkyl group and an aryl group, wherein the addition complex has a cone angle (θ deg) of 170 to 200, and an organoaluminum compound; wherein A 1 to A 4 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group of 1 to 15 carbon atoms, a cycloalkyl group, an aryl group, an ester group, an oxetanyl group, an alkoxy group, a trialkylsilyl group and a hydroxyl group, wherein A 1 to A 4 may be each bonded to a cyclic structure through a bond group of 0 to 10 carbon atoms, wherein said bond group is selected from the group consisting of an alkylene group of 1 to 20 carbon atoms, an oxygen atom, a nitrogen atom and a sulfur atom, wherein A 1 and A 2 may form an alkylidene group comprising 1 to 5 carbon atoms, a substituted or unsubstituted alicyclic or aromatic ring comprising 5 to 20 carbon atoms or a heterocyclic ring comprising 2 to 20 carbon atoms, wherein A 1 and A 3 may form a substituted or unsubstituted alicyclic or aromatic ring comprising 5 to 20 carbon atoms or a heterocyclic ring comprising 2 to 20 carbon atoms, and m is 0 or 1; to form the cycloolefin addition polymer.
