Abstract
Cross-linked aqueous dispersions and emulsions and method for producing casts of any desirable shape therefrom the dispersions comprising a water dissipatable polymer in an amount from 18 to 30 percent by weight based on the total weight of the composition; water in an amount from .[.67 to 30.]. .Iadd.30 to 80 .Iaddend.percent by weight based on the total weight of the composition; a source of multivalent metallic ions in an amount of 0.1 to 5 percent by weight based on the total weight of the composition; and humectant in an amount from 0.1 to 40 percent by weight based on the total weight of the composition and the emulsions comprising a water dissipatable polymer in an amount from 18 to 30 percent by weight based on the total weight of the composition; water in an amount from .[.67.]. .Iadd.30 .Iaddend.to 80 percent by weight based on the total weight of the composition; emollient oils in an amount from 0.1 to 25 percent by weight based on the total weight of the composition; a source of multivalent metallic ions in am amount from 0.1 to 5 percent by weight based on the total weight of the composition; humectants in an amount from 0.1 to 40 percent by weight based on the total w…
