| titleOfInvention | Method for producing copolyester |
| abstract | (57) [Abstract] [Object] The present invention relates to a method for producing a copolyester which forms fibers having high water absorption and water retention and capable of maintaining the high water absorption and water retention for a long period of time. When a polyester is produced by reacting at least one difunctional aromatic carboxylic acid or its ester-forming derivative with at least one diol compound, the compound of the general formula (I) or the general formula (II) The polyoxyalkylene group-containing compound shown is copolymerized with the dicarboxyarene sulfonic acid metal salt or its ester-forming derivative, and polycondensed until the intrinsic viscosity becomes 0.5 dl / g or more. This is a method for producing a copolyester. [Chemical 1] [Chemical 2] (In the formula, R 1 and R 3 represent a hydrocarbon group having 1 to 18 carbon atoms, R 2 and R 4 represent an ethylene group and / or a propylene group, respectively, and n 1 and R 4 represent an average degree of polymerization. It is a number from 10 to 100.) |
