PROCESS FOR PREPARING CLAY MINERAL POLYMER GELS OF REVERSIBLE WATER-ABSORBING CAPACITY, HAVING IMPROVED MECHANICAL PROPERTIES

摘要

Water swelling thixotropic clays of trilaminer structure or linear silicates are reacted with water soluble polymers in an aq. medium. If required the water content of the ensuing gel is opt. completely removed. One or several curable polymers are added to the mixt. at any stage of the reaction. These polymers are cross-linked on completion of reaction.
