Hydroxyhexafluoroisopropylnorbornene Block and Random Copolymers as Biobutanol Pervaporation Membranes

Norbornene block coplymer used as biobutanol prevaporation membrane

Professor Rick Register and Postdoctoral Research Associate Dong-Gyun Kim, in collaboration with researchers at Promerus LLC, have developed new permselective polymeric materials to enable the recovery and concentration of butanol from dilute aqueous solution, such as fermentation broth.  Energy-efficient recovery of butanol is an essential enabling technology for the large-scale production of butanol as both a chemical building block, and eventually, biofuel.  The permselective block copolymers are created by “living” vinyl addition polymerization of norbornene-type monomers with appropriately-chosen substituents.
