Abstract: The present invention relates to a gelation promoting agent when polymerizing a norbornene-based monomer in the presence of a metathesis polymerization catalyst, the gelation promoting agent obtained by mixing an activator of the metathesis polymerization catalyst and a norbornene-based monomer, wherein the gelation promoting agent consists essentially of a mixture of only two components of the activator and the above norbornene-based monomer; and a liquid formulation for reaction injection molding containing the gelation promoting agent. The gelation promoting agent of the present invention is added to a liquid formulation for reaction injection molding, thereby exhibiting effects that the gelation when the liquid formulation contacts a catalyst can be shortened. The liquid formulation for reaction injection molding of the present invention containing a gelation promoting agent is used as the liquid formulation for RIM method, thereby giving a molded article exhibiting effects that high mechanical strength is maintained and surface conditions are excellent can be manufactured, and effects that residual resins on a mold used can be reduced. The reaction injection-molded article of the present invention exhibits effects that high mechanical strength is maintained, and the surface conditions are excellent.
