Document Type and Number:
Japanese Patent JP2020002189
Kind Code:
A
Abstract:
To provide a method for producing a polyglycolic acid resin composition which has degradability even under a low-temperature environment and is excellent in moldability.SOLUTION: The method for producing a polyglycolic acid resin composition containing a polyglycolic acid resin and a degradation accelerator for the polyglycolic acid resin includes: a first kneading step of melt-kneading the polyglycolic acid resin; and a second kneading step of adding the degradation accelerator to the melt-kneaded polyglycolic acid resin and further melt-kneading it. The temperature of a kneaded product in the second kneading step is adjusted to 220°C or higher and 270°C or lower.SELECTED DRAWING: None
