  • Patent number: 9156953
    Abstract: To provide polyglycolic acid resin compositions having excellent moldability, and high barrier properties and transparency after molding, and molded articles therefrom. According to the present invention, a polylactic acid having a mass average molecular weight Mw of 100000 to 1000000 is added to a polyglycolic acid having a mass average molecular weight Mw of 100000 to 1000000 in a content of the polylactic acid of 5 to 30% by mass, and the mixture is melt-kneaded under, for example, a temperature condition of 230 to 270° C., thereby obtaining a resin composition having a temperature-lowering crystallization peak temperature Tc, measured by differential scanning calorimetry, of 3 to 18° C. lower than that of a polyglycolic acid only.
