| titleOfInvention | Method for producing lactone polymer |
| abstract | Provided is a method for efficiently producing a lactone polymer excellent in hue, hydrolysis resistance, and durability using a catalyst having a low environmental load. The method for producing a lactone polymer according to the present invention is a method for producing a lactone polymer, wherein a lactone polymer is obtained by ring-opening polymerization of a lactone compound, and a fatty acid zinc salt having 9 or more carbon atoms and a lactone compound as a catalyst. It is characterized by being used in the range of 1 to 500 ppm with respect to the total amount of initiator. As the fatty acid zinc salt having 9 or more carbon atoms constituting the catalyst, an unsaturated fatty acid zinc salt having 9 or more carbon atoms is preferable, and zinc undecylenate and / or zinc laurate are particularly preferable. Furthermore, it is preferable to use the initiator in the range of more than 0.5 mol and 120 mol or less with respect to 100 mol of the lactone compound. |
