| titleOfInvention | Polyester production method |
| abstract | Kind Code: A1 A method for producing a polyester capable of stably producing a polyester having an extremely high degree of clarity with little increase in foreign matter content even when a high-quality polyester having good electrostatic adhesion is continuously operated for a long period of time. It is to provide. Furthermore, the glycol distilled in the production process of the polyester can be recycled and reused in a highly economical manner, and can be stably produced continuously over a long period of time without deteriorating the quality of the polyester even if the circulation is reused. To provide a method for producing polyester. SOLUTION: At least a magnesium compound and a phosphorus compound are added from any one of a dicarboxylic acid mainly composed of an aromatic dicarboxylic acid and an alkylene glycol having 2 to 4 carbon atoms. A method for producing a polyester, wherein the polyester is filtered with a filter having a maximum pore size of 10 μm or less by a bubble point method and a filtration area of 4 to 200 m 2 .
