Description

ABSTRACT:
An improved superabsorbent polymer foam having a morphology to provide improved absorptive properties is disclosed. The foam preferably comprises a superabsorbent polymer formed from a substantially water-soluble, unsaturated monomer having neutralized carboxyl groups and a substantially water-soluble internal crosslinking agent. The monomer and crosslinking agent are expanded in the presence of a substantially water-insoluble blowing agent and a suitable solvent and reacted to form a superabsorbent polymer foam having substantially continuous, intercommunicating channels substantially throughout the foam and a relatively high surface area to mass ratio.
Methods for making the foam and absorbent products, members and articles containing the foam are also disclosed.
