Abstract

PURPOSE: To prepare a formed enteric product having high stability and formability, by hot-pressing a specific mixed ester of cellulose ether.
CONSTITUTION: An acidic succinyl and aliphatic monoacyl mixed ester of a cellulose ether having alkyl and/or hydroxyalky substituent groups (e.g. a reaction product of hydroxypropyl cellulose with succinic anhydride and acetic anhydride) is hot-pressed at 60W250°C to obtain a formed enteric product (e.g. enteric film, einteric capsule, etc.). Since the mixed ester can be formed easily by hot-pressing, it is not necessary to use organic solvents in the preparation of the objective product. The high stability of the ester prevents the decomposition of the product during the hot-pressing. Plasticizers are not necessarily incorporated in the forming composition because of the excellent flexibility of the ester. The product has high resistance to hydrolysis with moisture during storage.
