    摘要： Glycolide production through depolymerization of glycolic acid oligomer is stabilized by controlling impurities in the glycolic acid oligomer to allow economical and effective production of glycolide. More specifically, the depolymerization system is controlled to suppress an effective concentration (x+100y wt. %) of depolymerization-obstructing substances calculated as a total of a concentration calculated as diglycolic acid (of x wt. %) of hydroxyl group-free impurity carboxylic acids (A) and 100 times a concentration calculated as ammonia (of y wt. %) of nitrogen-containing substances (B), respectively with respect to the starting glycolic acid oligomer in the depolymerization system, to at most 15 wt. %.

    摘要： There is provided a method for producing a poly(arylene sulfide) in which a dihalo-aromatic compound and an alkali metal halide are polymerized by heating in an organic amide solvent, wherein the cooling time for the polymerization reaction system is significantly reduced. After the polymerization process, there is provided a cooling process for cooling the polymerization reaction system comprising a liquid phase containing the product poly (arylene sulfide) and the organic amide solvent and a vapor phase containing a gas component (A); and in the cooling process, the gas component (A) in the vapor phase is cooled while the content of a low boiling gas component (A1), which has a lower boiling point than water and exists in the gas component (A), is reduced in the vapor phase of the polymerization system.
