| titleOfInvention | Production method of polymer, polymer solution, and polymer |
| abstract | The present invention efficiently removes these metal residues from a polymer solution containing metal residues such as titanium, aluminum, lithium, etc., and obtains a purified polymer solution with less metal residues and good color tone and transparency. A polymer production method, a polymer solution obtained by the production method, and a polymer are provided. The method for producing a polymer according to the present invention comprises a step 1 of preparing a polymer solution containing one or more metals selected from the group consisting of aluminum, lithium, and titanium, the polymer solution, and the polymer solution. And a step 2 in which 0.1 to 10 times volume of water is mixed to obtain a mixed solution, and the aluminum content in the polymer contained in the polymer solution in the step 1 is less than 30 ppm When the pH of the aqueous phase of the mixed solution is adjusted to 10 or less in the step 2, and the aluminum content in the polymer contained in the polymer solution in the step 1 is 30 ppm or more and 200 ppm or less In the step 2, the pH of the aqueous phase of the mixed solution is adjusted to 5.5 or less, or 7 to 10. |
