ABSTRACT:
A water swellable foam matrix formed as a macroporous solid comprising a foam stabilizing agent and a polymer or copolymer of a free radical polymerizable hydrophilic olefin monomer crosslinked with about 0.1 to about 10% by weight of a multiolefin-functional crosslinking agent is described. The foam matrix is characterized by rapid swelling and high water swelling ratios.
