    摘要: A polyglycolic acid-based resin composition is formed by adding a relatively small amount of aromatic polyester resin to a polyglycolic acid resin. The thus-formed composition is provided with remarkably improved moisture resistance stability and hot-melt processability, and further improved stretchability, while retaining the excellent properties as represented by gas barrier property of the polyglycolic acid resin. As a result of stretching by utilizing the improved stretchability, a shaped product having an improved transparency can be obtained.

    摘要: Disclosed herein is a process for the production of an alkylene thioether-arylene thioether copolymer, which comprises copolymerizably reacting a compound having at least one alkali thiolate group and obtained by causing an alkali metal sulfide to act on a poly(arylene thioether) in a water-containing polar organic solvent so as to depolymerize the poly(arylene thioether) with a dihalogen-substituted aliphatic compound in a water-containing polar organic solvent.
