NORBORNENE MONOMER CONTAINING FLUID COMPOSITION FOR REACTION INJETION MOLDING, PROCESS FOR MANUFACTURING PRODUCTS OF REACTION INJECTION MOLDING, AND PRODUCTS OF REACTION INJECTION MOLDING
[PROBLEMS] To provide a norbornene monomer containing fluid composition for reaction injection molding which can attain excellent intimate blending and give products of desired shapes even when the shapes are complicated ones having bosses and/or ribs; a process for manufacturing products of reaction injection molding by the use of the fluid composition; and products of reaction injection molding obtained by the process. [MEANS FOR SOLVING PROBLEMS] A norbornene monomer containing fluid composition to be molded by reaction injection molding through in-mold bulk polymerization of the norbornene monomer, characterized by containing both a norbornene monomer and heat-expandable microcapsules each comprising a shell made of an α,β-ethylenically unsaturated acid derivative polymer having an acid group and a liquid blowing agent enveloped in the shell; a process for manufacturing products of reaction injection molding by the use of the fluid composition; and products of reaction injection molding obtained by the process.
