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. |
