Abstract
PURPOSE: The titled molded product expanding or shrinking with a definite form being analogously kept, during water absorption or dehydration, which comprises a high-water absorption resin having a crosslinkage.
CONSTITUTION: A molding compound prepared by the addition of a crosslinkage- forming agent such as a polymn. accelerator, a crosslinking agent or a catalyst, to a high-water absorption resin such as a high-water absorption acrylic resin, a prepolymer or a monomer thereof, is casted into a mold of a desired form and heated, to obtain a molded product with adequate flexibility.
EFFECT: Upon standing in water, the molded product expands several to several hundred times in volume keeping an analogous form, while when removed from the water and dried, it shrinks keeping an analogous form.
USE: Tops, humidity adjusting materials, etc.
