reaction injection molding liquid mixture, method for producing a reaction injection molded product, and reaction injection molded product

摘要

1/1 summary “reactive injection molding liquid wool mixture, method for producing a reaction injection molded product, and injection molded product in The present invention provides: a liquid reaction injection molding mixture, which contains a norbornene monomer, a polymerization catalyst. metastasis which includes a tungsten as the central metal, an activator and an ester compound represented by the formula (i), wherein the ratio of the mixture of the component to the activator (ether compound / activator ) is 0.7 / 1 to 30/1 according to the molar ratio, a method for producing a reaction injection molded body comprising a step in which reaction injection molding is carried out by subjecting this liquid reaction injection molding mixture to polymerization bulk in a mold; and a reaction injection molded body that is obtained by this production method. therefore, the present invention provides: a reaction reaction injection molding mixture which is capable of providing a reaction injection molded body. which has a good surface and excellent strength, leaving no resin residue on the surface of a mold when the reaction injection molded body is released from the mold; a method for producing a reaction injection molded body which utilizes this reaction reaction injection molding mixture; and a body shaped by reaction injection, which is obtained by this method. (In formula 14 (1), each of r -r independently represents an alkyl group having from 1 to 6 carbon atoms).
