Poly- epsilon -caprolactone resin and method for retarding hydrolysis rate thereof

摘要

A poly- epsilon -caprolactone resin having an enhanced stability to hydrolysis is obtained by ring-opening polymerization of epsilon -caprolactone with 0.01 to 5.0% by weight, based on the epsilon -caprolactone, of an epichlorohydrin-bisphenol A type epoxy compound of the formula: <IMAGE> +TR <IMAGE>
