Patent ID: 7241847

Claim:
A process for producing a cycloolefin addition polymer, comprising addition-polymerizing one or more cycloolefin monomers comprising a cycloolefin compound represented by formula (2)-1 or formula (2)-2, in the presence of a multi-component catalysts comprising: (a) a palladium compound, and (b) one or more phosphorus compounds selected from the group consisting of compounds (b-1) and (b-2): wherein (b-1) comprises a phosphonium salt represented by formula (b1): [PR 2 R 3 R 4 R 5 ]+[CA 1 ]− (b1) wherein P is a phosphorus atom, R 2 is a substituent selected from the group consisting of a hydrogen atom, an alkyl group of 1 to 20 carbon atoms, a cycloalkyl group and an aryl group, R 3 to R 5 are each independently a substituent selected from the group consisting of an alkyl group of 1 to 20 carbon atoms, a cycloalkyl group and an aryl group, and [CA 1 ] − is a counter anion selected from the group consisting of a carboxylic acid anion, a sulfonic acid anion and a superstrong acid anion comprising an atom selected from the group consisting of B, P Sb and F, wherein (b-2) comprises 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 R 1 and R 2 are each a substituent selected from the group consisting of an alkyl group of 1 to 10 carbon atoms, a cycloalkyl group and an aryl group, wherein X is selected from the group consisting of an alkoxy group of 1 to 5 carbon atoms and a halogen atom, wherein Y is a residue of a hydroxyl group of an aliphatic diol comprising 2 to 4 carbon atoms, wherein k is an integer of 0 to 2, and n is 0 or 1; to form the cycloolefin addition polymer.
