Abstract
The storage stability of a polymeric article susceptible to hydrolytic degradation, e.g., an absorbable suture, is improved by applying a storage stabilizing amount of a mixture comprising at least one water soluble hygroscopic polyhydroxy compound and/or ester thereof, e.g., glycerol, monoacetin, diacetin, and the like, and at least one compound having the general formula ##STR1## and hydreates thereof to the article as storage stabilizing agent, said agent being retained by the article prior to sealing of the enclosure in which the suture is packaged.
