There are photosensitive polymers which undergo transformation                  (isomerization, ring closure, etc.) upon irradiation by UV                      light.  Preliminary Japanese work indicated that the                            permeabilities of enzymes were reduced by a factor of ten when                  a polymer membrane was irradiated.  This research will explore                  and extend the concept to gas separations, to cover eight                       commercially important gases and a number of photosensitive                     polymer membranes.  The research will include                                   preparation/characterization of membranes, permeability                         (solubility and diffusivity) measurements, and interpretation                   of the data by existing theories.
