A mixing headwhich 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, a cap, and a mixing rotor. A plurality of protrusionsincludes first protrusionshaving a width in the axial direction of the mixing rotorlarger than that in the circumferential direction, and second protrusionshaving a width in the axial direction of the mixing rotorsmaller than that in the circumferential direction. First and second protrusion rowsandare alternately arranged, the first protrusion rowsbeing formed of the first protrusionsaligned at a predetermined interval, the second protrusion rowsbeing formed of the second protrusionsaligned at a predetermined interval.

Method for producing polymerization-reactive liquid formulation

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.

Polymerizable composition, cycloolefin-based polymer, and metal/resin composite

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.
