    摘要： A soft film, a sponge, or a sheet in the dried state is provided, which is capable of forming a hydrogel absorbing water or blood. The film is obtainable by preparing a film-state material in the dried state from either a solution of poly(acrylic acid) or a solution of polyvinylpyrrolidone, and bringing the film-state material into contact with the other remaining solution, and then drying or freeze-drying it.

    摘要： The present invention provides a polymer-combined drug having directional characteristics to digestive organs, wherein it comprises a medicine combined with a polymer which has an alkyleneoxy group as a repeating unit. The polymer-combined drug is produced by reacting a polyoxyalkylene glycol having one or more terminal functional groups and a medicine, if necessary in a solvent, and if necessary in the presence of a catalyst. It is able to administer the drug orally or by intravenous injection so as to maintain the concentration in blood stably for a long time, and to absorb or take in digestive organs such as the stomach and intestines directly.
