Abstract: The present invention relates to a norbornene-based crosslinked polymer containing at least one member selected from the group consisting of dicyclopentadiene-based monomer units, tetracyclododecene-based monomer units, and tricyclopentadiene-based monomer units in an amount of 50% by mass or more, wherein the norbornene-based crosslinked polymer has a glass transition temperature of 240° C. or higher. Further, the present invention relates to a method for producing a norbornene-based crosslinked polymer as defined above, including step (1): heating a blend containing at least one member of the above monomer components, and a metathesis polymerization catalyst to a temperature lower than a deactivation temperature of the metathesis polymerization catalyst to carry out a primary curing; and step (2): heating a cured product obtained in the step (1) to a temperature equal to or higher than the deactivation temperature of the above metathesis polymerization catalyst to carry out a secondary curing.

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.

Abstract: The present invention provides: a reaction injection molding liquid mixture comprising a norbornene-based monomer, a metathesis polymerization catalyst that includes tungsten as a center metal, an activator, and an ether compound represented by a formula (1), wherein R1 to R4 are independently an alkyl group having 1 to 6 carbon atoms, the reaction injection molding liquid mixture comprising the activator and the ether compound in a molar ratio (ether compound/activator) of 0.7/1 to 30/1. A reaction injection molding liquid mixture makes it possible to obtain a reaction injection molded product that has an excellent surface (surface state) and exhibits excellent strength while preventing a situation in which the resin remains on the surface of the mold when the resin is removed from the mold, a method for producing a reaction injection molded product using the same, and a reaction injection molded product obtained using the method.
