Abstract: Provided is a method that can produce a resin porous material from a water-insoluble polymer in a small number of steps while suppressing the formation of skin layers. The production method of a resin porous material disclosed herein includes preparing a solution of a water-insoluble polymer in a mixed solvent including a good solvent of the water-insoluble polymer and a poor solvent of the water-insoluble polymer, and drying the solution to remove the mixed solvent. The poor solvent has a higher boiling point than the good solvent. The drying the solution is performed using superheated water vapor.

Abstract: The invention relates to a method for producing particles with pore structures, by means of a hybrid process of atomization via drying-cooling, from a water-in-oil-type emulsion of a composition of a non-solubilized and in melt state matrix. The production method comprises: i) forming a water-in-oil-type emulsion consisting of a composition of a solvent that is aqueous or soluble in water (dispersed phase) and a composition of a non-solubilized and in melt state matrix (continuous phase); ii) forming discrete particles from the emulsion via atomization, using a flow of gas at high pressure and temperature; iii) immediately removing the solvent via evaporation; and iv) subsequently cooling the formed discrete particles, resulting in porous particles that are substantially free from solvents.

Abstract: The present disclosure is directed to a closed cell foam matrix for delivering oxygen containing a superabsorbent material oxygen entrapped within the superabsorbent material. The superabsorbent material has at least 15 percent by mass monoethylenically unsaturated carboxylic, sulphonic or phosphoric acid or salts thereof, an acrylate or methacrylate ester that contains an alkoxysilane functionality, and a copolymerizable hydrophilic glycol containing ester monomer. To produce the closed cell foam matrix for delivering oxygen, an alkali hydroxide catalyst is added to the superabsorbent material to form a hydrogel layer. Then, an oxygen precursor is added to the hydrogel layer. The hydrogel layer is heated to produce oxygen by reacting the alkali hydroxide catalyst and the oxygen precursor thereby entrapping the oxygen in the formed closed cell foam matrix.
