Conventionally, water-soluble polyesters have been useful for easily soluble polymers that can be dissolved and removed from starches, adhesives, and synthetic fibers composed of multiple components.
Polyesters are known in which an ester-forming sulfonic acid metal salt compound is copolymerized with low-molecular weight or high-molecular weight polyethylene glycol C (hereinafter abbreviated as FEQ). However, when using low molecular weight PEG such as diethylene glycol or triethylene glycol, PEG tends to distill out of the reaction system during the polycondensation reaction of polyester, making it difficult to control the amount of PEG in the polyester produced. Moreover, there is a problem in that the distillate is significantly contaminated. On the other hand, P.E.
As the molecular weight of G increases, this problem related to distillation decreases, but the light resistance of the PEG copolymerized polyester decreases. Fi becomes noticeable. Further, when the PEQ copolymer polyester is dissolved and removed from the fibers, some of the polyester may remain uneluted, but in such a case, the above-mentioned decrease in light resistance causes a significant decrease in product quality.

If the amount is less than 1 mole, preferably 5 to 40 moles, the water solubility of the obtained polyester will decrease and the stability as a solution will also deteriorate. If the amount is more than 50 mol, the melt viscosity during polyester polymerization becomes extremely high, making it difficult to increase the degree of polymerization. Further, the chemical stability of the obtained polyester is also lowered, which is not preferable. Note that if the metal layer of the sulfonate compound is a polyvalent metal other than an alkali metal, the water solubility of the obtained polyester will be significantly reduced, which is not preferable.
