METHOD FOR PREPARING WATER NON-SOLUBLE GELS IN SOLID STATE AND WATER NON-SOLUBLE GELS PREPARED BY SAME METHOD

摘要

PURPOSE: A method for manufacturing a water insoluble gel composition is provided to maintain the shape and size of water soluble polymers and to obtain a composition of high quality. CONSTITUTION: A method for preparing a water insoluble gel composition comprises: a step of inputting water, dispersion agent, water insoluble polymers, pH adjusting agent, and crosslinking agent to prepare a composition; and a step of removing water and dispersion agent from the composition. The water soluble polymers contain carboxyl group(-COOH) or carboxylate and hydroxy group(-OH) or hydroxy salt. The dispersion agent is added in 100-2,500 wt%. The water and dispersion agent are removed by decompressing or heating the composition.
