PROBLEM TO BE SOLVED: To provide a two-component catalyst system suitable for ring-opening metathesis polymerization of strained cycloolefins by the RIM method. SOLUTION: At least two components (a) and (b) Catalyst. (A): RuX 2 (L 1 ) m (L 2 ) n (L 3 ) o (L 4 ) p (I) or ARuX 2 (L 1 ) r (L 2 ) s (II) [L 1 to L 4 are C1-18 alkyl cyanide, C6-24 aralkyl cyanide, tertiary amine, P Tertiary phosphine, phosphite, containing no secondary alkyl or cycloalkyl group attached to the atom; X is a halogen; A is an arene; m, n, o, p is 0-4, 2 ≦ m + n + o + p ≤4, r, s is 0- 2 wherein 1 ≦ r + s ≦ 2] and (b) a tertiary phosphine containing at least one secondary alkyl or cycloalkyl group bonded to a P atom. |
