    • PROBLEM TO BE SOLVED: To provide a method for producing a polymer in which a deviation of viscosity is small even when mixing raw materials having different viscosity together, so that a polymer having a relatively narrow molecular weight distribution, especially preferably polyurethane, is stably and efficiently produced. SOLUTION: The method for producing a polymer is provided, in which after a fluid (I) containing prepolymer which has a reactive functional group at the molecule terminal is mixed with a fluid (II) containing a compound which has two or more functional groups reactive with the reactive functional group in the molecule, using a micromixer having structure capable of mixing the fluids (I) and (II), in a liquid-tight pressurized state in the channel, the mixture is further distributed while being delivered through the channel whose channel cross-sectional area is reduced in the flow direction.

    • PROBLEM TO BE SOLVED: To provide a method for safely and efficiently producing a polyurethane with a narrow molecular weight distribution and a small remaining amount of an organic polyisocyanate. SOLUTION: In the method for producing a polyurethane, a fluid containing an organic polyisocyanate and an active hydrogen-containing compound is passed through a microtubule of a reaction vessel, in which microtubular channels are formed, while the channel is in a liquid-tight pressurized state. It is especially desired that the reaction is performed while the reaction selectivity of an isocyanate group or a hydroxyl group is controlled by continuously controlling Reynolds Number between 5 and 1000.
