    摘要: 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.
