ABSTRACT:
A hydrous gel consisting essentially of a heat-moldable w/o emulsion comprising about 15 to about 95% by weight of a continuous phase of an A-B-A type teleblock copolymeric elastomer and an oil component and about 85 to about 5% by weight of an emulsified dispersed water phase. The hydrous gel is prepared by dissolving the teleblock copolymeric elastomer in an excess of the oil component by heating, adding an emulsifier and water to the solution to disperse the water therein and to form the w/o emulsion, and then cooling the resulting emulsion to room temperature. The hydrous gel finds a wide range of utility, for example, as an insulator, especially to maintain low or high temperature environments, as a fireproofing material, as a heat absorbant, and as a hospital mat.
