Abstract: Disclosed is an asphaltic elastomer and a method for its preparation. The asphaltic elastomer is synthesized from ingredients which are blended. These ingredients include an aqueous asphaltic phase, a polyisocyanate prepolymer, and optionally an organic cosolvent effective in compatibilizing the polyisocyanate prepolymer and water. The proportion of water from the asphaltic phase or as added being such that the molar ratio of water to isocyanate groups is greater than 1. The polyisocyanate prepolymer is formed from the reaction of an organic polyisocyanate and an organic polyether polyol containing at least about 40 weight percent ethylene oxide units.

Abstract: Disclosed is a sculpted, hand-squeezable toy which possesses dimensional memory and has a predetermined dimensional memory restoration time. The toy is made by blending a foamable hydrophilic polyurethane isocyanate-functional prepolymer, a vinyl or acylic polymer emulsion recovery rate modifier, water, and an organic cosolvent. The blend then is charged to a mold for the foamed toy to be made therein. The proportion of organic cosolvent present and the temperature of the blend being molded are variables for determining the predetermined dimensional memory restoration time of the toy after it has been squeezed.
