1234YF– AND 1234ZE–BASED POLYMERIC MEMBRANE MATERIALS, MEMBRANE PREPARATIONS AND USES THEREOF

摘要

The present invention generally relates to polymeric membrane materials formed, at least in part, from monomeric material selected from 2,3,3,3-tetrafluoropropene (CF3CF=CH2, HFO-1234yf) or trans-1,3,3,3-tetrafluoropropene (CF3CH=CFH, HFO-1234ze), and to membrane preparations and uses thereof in water desalination, filtration, membrane distillation, pervaporation, and selective gas separation.
