Document Type and Number:
WIPO Patent Application WO/2018/043531
Kind Code:
A1
Abstract:
Provided is a method for producing a water-insoluble moulded body which maintains the inherent properties of a polyanionic polysaccharide used as a starting material thereof, exhibits high safety due to not needing the use of a chemical crosslinking agent, and exhibits moderate pliability (flexibility), stretchability, and adhesiveness. The method for producing the water-insoluble moulded body is provided with a step in which a starting material moulded body comprising a starting material including a water-soluble salt of a polyanionic polysaccharide, and at least 0.2 mass% of an acid component, or a starting material moulded body comprising a starting material including a water-soluble salt of a polyanionic polysaccharide, and an alcohol (excluding glycerin), is treated with a treatment liquid including an acid anhydride, to make the starting material moulded body water-insoluble.
