Depolymerization method of polyester |
| abstract |
(57) Abstract: A method for producing a macrocyclic polyester oligomer substantially free of hydroxybutyl-terminated linear impurities is provided. SOLUTION: The linear polyester is depolymerized by bringing the linear polyester into contact with an organic solvent substantially free of oxygen and water and a depolymerization catalyst to form a macrocyclic polyester oligomer. |
