Patent ID: 6911507

Claim:
A method for producing a cyclic olefinic addition polymer, comprising polymerizing a cyclic olefin containing at least one substituted norbornene represented by the following formula (2) by addition polymerization in a hydrocarbon solvent, using a polymerization catalyst component containing (i) a transition metal compound represented by the following formula (1), (ii) a Lewis acid compound and (iii) an alkyl aluminoxane: (L 1 MX)(An) (1) (in formula (1), M is a groups 8 to 10 transition metal in the periodic table, L is a neutral ligand or a solvent molecule, 1 is from 0 to 3, X is a β-diketonate anion or a carboxylic acid anion having a linear or branched alkyl group having 1 to 12 carbon atoms, and An is a non-coordinating or weakly coordinating anion) (in formula (2), at least one of A 1 , A 2 , A 3 and A 4 is a polar group represented by —(CR 1 R 2 ) q Z, and the others, which are the same or different, each represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 10 carbon atoms, a haloalkyl group, an aralkyl group, a cycloalkcyl group or an aryl group, wherein Z represents —C(O)R 3 , —OC(O)R 4 , —C(O)OR 5 or —SiY 1 Y 2 Y 3 , R 1 to R 5 , which are the same or different, each represents a hydrogen atom, a hydrocarbon group having 1 to 10 carbon atoms or a halogenated hydrocarbon group; Y 1 to Y 3 are the same or different, at least one is a halogen atom, an alkoxyl group, an allyloxy group or a siloxy group, and the others each represents a hydrogen atom, a hydrocarbon group having 1 to 10 carbon atoms or a halogenated hydrocarbon group; A 1 and A 2 , or A 1 and A 3 may be cyclized to form a lactone or an acid anhydride; and p and q each represent an integer of 0 to 3).
