Abstract: The present invention features a method for the formation of superporous hydrogels using an ion-equilibration technique. Anionic polysaccharides are included in the hydrogel reaction mixture and cations are introduced either during or after hydrogel formation. Properties of the resulting hydrogel can be subsequently adjusted by treating the cation-complexed gel with a different cation or cation mixture under equilibrating conditions. It has been found that by properly adjusting the cations and the sequence in which they are used in the equilibration process, superporous hydrogels can be formed that are highly absorbent while maintaining favorable structural properties, including strength, ruggedness, and resiliency. It has also been found that applying appropriate dehydration conditions to them after their formation can further stabilize the superporous hydrogels formed by the method of the invention.

Abstract: Porous membranes having a micro phase separation structure and showing a light transmittance at the wavelength of 400 nm of not less than 30% are obtained by the dry phase conversion method comprising drying a coating layer of a dope containing a polymer, a good solvent for the polymer and a poor solvent for the polymer which solvent has a higher boiling point than the good solvent. The polymer includes cellulose derivatives, vinyl-series polymers such as acrylonitrile-series polymers and (meth)acrylic acid ester-series polymers, polysulfone-series polymers, and the like. The porous polymer membranes have a porosity of 10 to 60%, a mean pore size of about 0.002 to 0.35 &mgr;m and a maximum pore size of not greater than 0.4 &mgr;m. These porous membranes shows not only excellent transparency but also high productivity.
