PURPOSE:To prepare easily various kinds of bioabsorbable molded items consisting of an aliph. polyester by molding a soln. wherein a polymer is dissolved in a solvent into a desired shape, evaporating the solvent and heat- treating it at 60-120 deg.C. CONSTITUTION:A soln. wherein a polymer is dissolved in a solvent is molded into a desired shape and heat treatment is performed at 60-120 deg.C at the same time when the solvent is evaporated or after solvent evaporation. Namely, if a molded item obtd. by molding from a soln. is heat-treated at 60-120 deg.C, the molded item is not softened or hardly softened when it is brought into contact with a living body. Therefore, it can be used for a purpose for keeping or fixing a living tissue for a certain period. It is thereby possible to prepare a molded item which can keep an enough rigidity for a certain period even if it is applied to a living body by means of a soln. molding. |
