The reaction undiluted solution for reaction injection molding, polymerization reaction injection molding manner and reaction

摘要

PROBLEM TO BE SOLVED: To provide a reaction injection molded article having no air bubbles in the inside of the molded article without imposing an undue burden on equipment and with a simple formulation.;SOLUTION: A reactive stock solution (A) for reaction injection molding is used for reaction injection molding by subjecting a norbornene-based monomer to bulk polymerization within a mold and comprises at least a norbornene-based monomer, a non-basic filler and a Shiff base coordinated metathesis polymerization catalyst represented by formula (1). A reaction injection molding method comprises injecting a blending solution comprising as an essential component the reactive stock solution for reaction injection molding (A) into a mold and carrying out bulk polymerization within the mold. A reaction injection molded article is produced by the reactive injection molding method.;COPYRIGHT: (C)2010,JPO&INPIT
