Solid poly-amphiphilic polymer having use in a separation process.

摘要

The present invention is directed to a solid poly-amphiphilic polymer. The polymer may be (1) a continuous film (a) which is strengthened sufficiently by cross-linking to be used alone and/or supported on a frame, (b) overlaid and/or cast on a porous hydrophobic support or (2) introduced into the pores of a microporous hydrophobic membrane. The present invention is also a process for selectively removing a dissolved species (solute or target compound) from an aqueous solution or from a gaseous stream comprising contacting said aqueous solution or gaseous stream having the dissolved species and an aqueous stripping solution or other means for removing said species with opposite sides or surfaces.
