Reaction injection molding liquid, reaction injection molding production method and reaction injection molding

摘要

The present invention comprises a norbornene-based monomer, a metathesis polymerization catalyst having tungsten as a central metal, an activator, and an ether compound represented by the following formula (1), and the blending ratio of the activator and the compound is A reaction injection molding compound liquid having a molar ratio (ether compound / activator) of 0.7 / 1 to 30/1; a step of subjecting the reaction injection molding compound liquid to bulk polymerization in a mold and performing reaction injection molding And a reaction injection molded article obtained by the production method. According to the present invention, there is no resin residue on the mold surface at the time of mold release, a reaction injection molding compound liquid capable of obtaining a reaction injection molded article having a good surface and excellent strength, and a reaction using the same. A method for producing an injection-molded article and a reaction injection-molded article obtained by this method are provided. (In the formula, R1 to R4 each independently represents an alkyl group having 1 to 6 carbon atoms.)
