| abstract | The present invention relates to a method for producing an epihalohydrin polymer, wherein a solution of a nitrogen-containing epihalohydrin polymer is produced by the reaction of a nitrogen-containing precursor selected from the group consisting of amines, poly-amines, polyaminoamides, polyurethanes and mixtures thereof with epihalohydrin. And the method includes a purification step for removing organic impurities from the solution in which the epihalohydrin polymer is produced, wherein the purification step fluidizes the epihalohydrin polymer solution under liquid, supercritical or near supercritical conditions. Extracting organic impurities into the fluid from the epihalohydrin polymer solution in contact with the fluid, removing the organic impurity-rich fluid from the epihalohydrin polymer solution, and separating the extracted impurities from the removed fluid; Fluid is at atmospheric pressure and room temperature (about 25 ° C In about the manufacturing method characterized by comprising the substance which is gaseous. The present invention also relates to a method for purifying a solution of a nitrogen-containing epihalohydrin polymer. [Selection] Figure 1 |
