摘要： Disclosed are a method for preparing hydroxypropyl methylcellulose acetate succinate (HPMCAS) grains and HPMCAS grains. The disclosed method for preparing HPMCAS grains comprises: a step of esterifying hydroxypropyl methylcellulose (HPMC), acetic anhydride, and succinic anhydride in a reaction medium in the presence of a catalyst so as to obtain a reaction solution containing HPMCAS (esterification step); and a step of continuously or intermittently putting the reaction solution into water so as to form grains (granulating step).

摘要： The present invention relates to a method of preparing a dry hydrogel sheet including the steps of: preparing a cellulose ether dispersion solution; transferring the dispersion solution to a coater while maintaining the temperature of the dispersion solution in the range of a gelation temperature of the dispersion solution to a boiling point of a dispersion medium; applying the dispersion solution transferred to the coater as a sheet; preparing a hydrogel sheet by cooling the applied dispersion solution to induce gelation; and drying the hydrogel sheet. Since the dry hydrogel sheet prepared by the method has a low moisture content, it is possible to ensure the stability of active ingredients, quantify functional components to be applied to the dry hydrogel sheet, and ensure the uniformity of the surface appearance and thickness of the dry hydrogel sheet, which results in the improvement of the quality of a final product.
