| titleOfInvention | Method for producing polyethylene naphthalate |
| abstract | [PROBLEMS] To significantly reduce molecular weight reduction (decrease in intrinsic viscosity) and hue deterioration (color b value) due to thermal deterioration during heating and melting, and low acetaldehyde content, productivity, heat resistance, mechanical strength, and Another object of the present invention is to provide polyethylene naphthalate used for polyester fibers, molded articles, sheets and films having excellent moldability. The above problem can be solved by a method for producing polyethylene naphthalate, wherein polyethylene naphthalate is brought into contact with an aqueous solution of an alkali metal salt and / or an alkaline earth metal salt having a concentration of 1 ppm to 10 wt%. [Selection figure] None |
