Abstract: A mixing head 3 which mixes a first preparative liquid formulation containing a norbornene-based monomer with a second preparative liquid formulation containing a metathesis polymerization catalyst includes a casing 4, a cap 7, and a mixing rotor 6. A plurality of protrusions 622 includes first protrusions 622a having a width in the axial direction of the mixing rotor 6 larger than that in the circumferential direction, and second protrusions 622b having a width in the axial direction of the mixing rotor 6 smaller than that in the circumferential direction. First and second protrusion rows 623a and 623b are alternately arranged, the first protrusion rows 623a being formed of the first protrusions 622a aligned at a predetermined interval, the second protrusion rows 623b being formed of the second protrusions 622b aligned at a predetermined interval.

Abstract: Provided is a polymerizable composition comprising a cycloolefin-based monomer having a specific structure, a silane coupling agent having at least one hydrocarbon group having a norbornene structure, and a metathesis polymerization catalyst.

Abstract: Provided is a surface-coated reinforcing material which, when used in a fluid composition for reaction injection molding, causes substantially no increase in the viscosity of said fluid composition and can be well dispersed therein, and can improve the rigidity of an article obtained by reaction injection molding the same. The surface-coated reinforcing material is provided, on the surface of a reinforcing material, with laminated coating layers consisting of one or more coating layers (A), which comprise a silane coupling agent (I) having at least one hydrocarbon group having a norbornene structure, and one or more coating layers (B), which comprise a coupling agent other than the silane coupling agent (I) and/or a fatty acid.
