PROBLEM TO BE SOLVED: To provide dicyclopentadiene which is suitable as a storage-stable two-component catalyst for ring-opening metathesis polymerization of cyclopentadiene adduct, and which has a short reaction time, high enthalpy of reaction and very small weight loss. And other cyclopentadiene adducts. SOLUTION: (a) Ruthenium or osmium phosphine complex [for example, (C 6 H 11 ) 3 P (p-cymene) R uCl 2 ] and (b) alkyne (eg, 1-octyne, Phenylethyne). |
