Process for producing cycloolefin addition polymer

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 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)
• [PR2R3R4R5]+[CA1]− (b1)
• wherein P is a phosphorus atom,
• R2 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,
• R3 to R5 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
• [CA1]− 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 A1 to A4 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 A1 to A4 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 A1 and A2 may form an alkylidene group comprising 1 to 5 carbon atoms, a substituted or unsubstituted alicyclic or aromatic ring of comprising 5 to 20 carbon atoms or a heterocyclic ring of comprising 2 to 20 carbon atoms,
• wherein A1 and A3 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
• wherein m is 0 or 1:
• to form the cycloolefin addition polymer.
