Abstract
Absorbent, elastomeric materials and methods of making absorbent, elastomeric materials. The absorbent, elastomeric materials include an elastomeric substrate and a superabsorbent polymer non-adhesively attached to the substrate. The elastomeric substrate includes at least one nonwoven, and may include, for example, elastic strands, elastic film, and/or elastic foam between layers of nonwoven. The superabsorbent polymer includes particles that either encase fibers of the nonwoven or bond themselves to fibers of the nonwoven.
