Method for producing aliphatic polyester |
| abstract |
An object of the present invention is to provide a method for producing an aliphatic polyester in which energy during production and impurities such as metals in the polymer are reduced, and the resulting aliphatic polyester can have a high molecular weight and / or a small molecular weight distribution. A method for producing an aliphatic polyester, comprising ring-opening polymerization of a cyclic ester in an organic solvent in the presence of a compound having a guanidine skeleton represented by the following chemical formula (1): Either one or both of R 1 and R 2 and R 3 and R 4 may be linked to each other to form a ring. [Selection figure] None |
