Abstract: An object of this invention is to provide a method for the production of a porous material by polymerizing a water-in-oil type high internal phase emulsion in a briefer time than a conventional technique without impairing the stability of the emulsion. The object of this invention can be accomplished by a method for the production of a porous material comprising a step of polymerizing a water-in-oil type high internal phase emulsion containing a polymerization initiator, wherein the polymerization initiator is a redox type initiator combining a water-soluble oxidizing agent and a reducing agent, the reducing agent is preparatorily added to form the emulsion, and thereafter the water-soluble oxidizing agent is added to the emulsion to polymerize the added emulsion.

Abstract: A superabsorbent foam material is made by a water-in-oil high internal phase emulsion polymerization comprising the steps of (a) dissolving an organic solvent-soluble surfactant in a water-insoluble monomer to form an organic phase; (b) blending the-organic phase with an aqueous phase using high shear mixing to form an emulsion, said aqueous phase comprising a water-soluble polymer, a cross-linking agent, and water; (c) polymerizing the water-insoluble monomer in the organic phase; (d) cross-linking the water-soluble polymer in the aqueous phase; and (e) final curing and drying the resulting foam.
