Abstract

PURPOSE: To produce a sponge which has a uniform number of holes and an even hole size and is useful to a medical sponge-like porous base material, by drying by freezing an emulsion produced as a result of a volite organic solvent being added to a water phase containing a high molecular substance.
CONSTITUTION: A water phase is produced by dissolving or gelling in water a high molecular substance, an emulsifier, or other component such as a multivalent alcohol if necessary. An oil phase is produced by dissolving a volite organic solvent and together with a component such as medical substances if necessary. The oil phase is then added to the water phase to prepare an O/W type emulsion which transmutes the water phase into a dispersant and the oil phase into a dispersoid. The O/W type emulsion so obtained is dried by freezing, a desired sponge being produced by perfectly volatizing aforesaid solvent thereupon. A natural high molecule such as gum arabic, a semisynthetic high molecule such as methyl cellulose, and synthetic high molecule such as polyvinyl alcohol can be recommended to be used as the high molecule.
