A liquid formulation for reaction injection molding in which a norbornene-based monomer is polymerized in the presence of a metathesis polymerization catalyst in which the central metal is tungsten. The liquid formulation contains a norbornene-based monomer, a catalyst activator, and an ether compound represented by formula (1), and is obtained by mixing the norbornene-based monomer and the activator in the presence of at least the ether compound. The liquid formulation for reaction injection molding is suitable for use in the field of manufacturing reaction injectionmolded bodies. A reaction injection moldedbody of the present invention exhibits excellent mechanical properties and product surface finishing, and therefore is suitable for use in applications such as automobile parts and materials for household equipment. |
