Abstract:
1. 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): wherein P is a phosphorus atom, R R [CA 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 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.
