Abstract: An interlayer film for laminated glass of the present invention has an average storage modulus (G′) at 110 to 150° C. measured at a frequency of 1 Hz in a shear mode of 15000 Pa or less, and has an adhesive strength of 0.3 N/mm2 or more as measured in a cross peeling test performed under the following conditions on a cross peeling test sample produced by a predetermined method. Cross peeling test: A maximum load (N) when the polycarbonate plate glass is peeled from the clear float plate glass in a direction perpendicular to an adhesive surface at a rate of 10 mm/min at 23° C. is measured, and that measured maximum load (N) is taken as the adhesive strength.

Abstract: The mixing system includes a first container filled with a polyol composition, a second container filled with an isocyanate composition, and a stationary mixer configured to mix the polyol composition discharged from the first container and the isocyanate composition discharged from the second container. The polyol composition includes a polyol, a catalyst, and a low boiling point compound having a boiling point of less than 0° C. The isocyanate composition includes an isocyanate compound and a low boiling point compound having a boiling point of less than 0° C. The first container and the second container each have an internal pressure in a range of 0.3 to 1.0 MPa at 35° C., and a mixer portion of the stationary mixer has a length of 30 to 230 mm. A mixing system can be provided that enhances the mixability of a polyol composition and a polyisocyanate composition in a stationary mixer and prevents curing in the stationary mixer.
