ABSTRACT:
A hydrous gel consisting essentially of a water-in-oil dispersion cured with a crosslinking agent. The dispersion comprises a rubber component in which water is dispersed in the form of droplets in the presence of a surfactant. The rubber component is based on a liquid polyisoprene rubber having a cis-1,4 content of not less than 70% and a molecular weight of 8,000 to 120,000 or a modified polyisoprene rubber which is an adduct of the above-mentioned liquid polyisoprene rubber and maleic anhydride or a derivative thereof. The hydrous gel provides cold- and heat-retaining materials, perfume-retaining materials, adhesives for medical use, poultices and shock-absorbing materials.
