Abstract
An improved gel comprises a first polymer that dissolves, disperses or hydrates in hot water and forms or can be made to form a rigid gel on cooling, a second polymer that is insoluble in hot water and that dissolves or hydrates on cooling and is compatible with said hot water soluble polymer, and water. The gel is made by combining the first polymer and water, heating the resulting solution enough that the first polymer dissolves or hydrates, adding the hot water insoluble polymer, and then cooling.
