Abstract
Official abstract text for this publication.
A hydrogel having excellent mechanical properties and capable of being produced simply by using and mixing an industrially easily obtainable polymer having high versatility and clay particles, and to provide a method of producing the hydrogel. A hydrogel-forming composition is characterized by containing a polyelectrolyte, clay particles, and a dispersant for the clay particles.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hydrogel-forming composition, comprising: a polyelectrolyte; clay particles; and a dispersant for the clay particles; wherein: the polyelectrolyte has a weight average molecular weight of 250,000 to 10,000,000; and the dispersant is a dispersant for water-swelling silicic acid salt particles. 2. The hydrogel-forming composition according to claim 1 , wherein the polyelectrolyte is a polyelectrolyte having an or…
