BLEND POLYMERIC MEMBRANES CONTAINING FLUORINATED ETHYLENE-PROPYLENE POLYMERS FOR GAS SEPARATIONS |
摘要 |
The present invention generally relates to gas separation membranes and, in particular, to high selectivity fluorinated ethylene-propylene polymer-comprising polymeric blend membranes for gas separations. The polymeric blend membrane comprises a fluorinated ethylene-propylene polymer and a second polymer different from the fluorinated ethylene-propylene polymer. The fluorinated ethylene-propylene polymers in the current invention are copolymers comprising 10 to 99 mol% 2,3,3,3-tetrafluoropropene-based structural units and 1 to 90 mol% vinylidene fluoride-based structural units. The second polymer different from the fluorinated ethylene-propylene polymer is selected from a low cost, easily processable glassy polymer. |
