| titleOfInvention | Method for producing polyester and polyester obtained therefrom |
| abstract | [Problem] To provide a production method capable of stably producing polyester having good electrostatic adhesion, little increase in foreign matter content, and extremely high clarity. SOLUTION: A plurality of transfer lines provided with a stirring in-line mixer are branched between reaction tanks in a process for producing polyester by a continuous polycondensation method, and at least one of the branch lines is used to intermediate a polyester. In the method of continuously producing polyester by adding alkaline earth metal to an in-line mixer installed in the line where the intermediate flows, the obtained polyester is dissolved in a solvent, and the solution is filtered with a membrane filter. When the amount of alkaline earth metal in the residue on the filter exceeds the specified amount, the flow path of the polyester intermediate is switched, and at the same time, the addition of the alkaline earth metal compound is changed to an in-line mixer installed in the switched flow path. And the manufacturing method of polyester which continues continuous production. [Selection figure] None |
