Method for producing cyclic polyester oligomer and method for producing polyester |
| abstract |
(57) [Summary] (Problem corrected) [PROBLEMS] To produce a cyclic polyester oligomer which is more economical in producing a highly polymerized polyester than a conventionally known production method. Kind Code: A1 In the production of a cyclic polyester oligomer, a linear molar ratio in which the charged molar ratio of a diol component / dicarboxylic acid component is 1.0 to 1.6 when an esterification reaction between a dicarboxylic acid and a diol is performed. A method for producing a cyclic polyester oligomer, comprising using a polyester oligomer. Further, a method of producing a polyester by ring-opening polymerization of the obtained cyclic polyester oligomer. |
