Abstract
A method of controlling a moisture resistance of polyglycolic acid resin, by controlling a total carboxyl group-source concentration including a contribution of residual glycolide. As a result, a moisture resistance governing the change of strength with time of the polyglycolic acid resin is controlled at a good accuracy.
