    Abstract: The invention relates to a method for removing a process solvent (P-sol) from a polymer extrudate, especially in connection with a process for producing a microporous membrane. The method involves contacting the extrudate with chlorinated hydrocarbon (CHC) and hydrofluoroether (HFE) in a first stage; contacting the extrudate from the first stage with HFE in a second stage; combining the first and second waste streams and then separating the P-sol from the combined streams to make an HFE-CHC stream; cooling the HFE-CHC stream to make an HFE-rich phase and a CHC-rich phase; and conducting the CHC-rich phase and/or the HFE-rich phase to step (A).

    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.
