Abstract

PURPOSE: To preserve stably a swollen molded article over a long period of time, by a method wherein a molded article composed of a rubber or a resin is contacted with an org. solvent having affinity with the molded article to swell the molded article, and the resulting swollen molded article is immersed in a preservation liquid which does not have affinity with the article to preserve the article.
CONSTITUTION: A molded article obtd. from natural rubber, silicone rubber or polyvinyl chloride is contacted with an org. solvent (e.g. Freon 22 or hexamethyldisiloxane) having affinity with the molded article to swell the molded article in order to produce an original from-restoring molded article (e.g. cold shrinking tube). Then the resulting molded article is immersed in a preservation liquid (e.g. water or a saturated soln. of ethyl acetate) which does not have affinity with the molded article and the org. solvent to preserve the article, whereby the form-restoring function can be preserved safely and stably over a long period of time.
