| titleOfInvention | Method for producing block copolymerized polyester |
| abstract | (57) [Problem] To produce a block copolymer polyester for fibers, films, and resins, by using a nitrogen-containing compound as a catalyst, to produce a polyester having a small amount of catalyst residues and a good block property without deteriorating quality. A method of manufacturing is provided. SOLUTION: In synthesizing a block copolymer having an aromatic polyester and an aliphatic polyester as a block, a transesterification reaction is carried out in the presence of a specific nitrogen-containing organic compound catalyst to produce a polymer having a high block property. |
