摘要

rilgye nitro acrylic polymer with a solvent to be dissolved uniformly and efficiently and also , the clogging of the filter and the spinning nozzle is suppressed, there is provided a method of manufacturing the night rilgye polymer solution can be prepared by a nitro rilgye acrylic polymer solution with an acrylic stably. A mixture of said polymer and a solvent, fed to the distribution chamber of the cylinder and the front end unit having a rotor which rotates within a cylinder, to rotate the rotor under the conditions given the shearing force to the mixture and, thereafter, heating the obtained mixture Night rilgye in the manufacture of acrylic polymer solution to obtain an acrylic polymer solution with a night rilgye way: W = (W ₁ -W ₂ ) / M 0.12 (kWh / kg). W ₁ , W ₂ , M is defined in the specification. Or, by a W 1.60, the heating may be carried out. ;
