Membranes prepared from blend of polybenzimidazole with polyarylates |
| abstract |
This invention discloses novel membranes comprised of a blend of polyarylate and polybenzimidazole polymers. A membrane prepared from the blend of polybenzimidazole and polyarylate polymers exhibits enhanced properties over membranes prepared solely from either a polyarylate or a polybenzimidazole polymer. The addition of the polyarylate to the polybenzimidazole membrane allows the composition to be more thermally processable and less susceptible to moisture. The presence of the polybenzimidazole renders the polyarylate less reactive to solvents and increases its thermal stability. In addition, it has been surprisingly found that membranes prepared from the polybenzimidazole polyarylate blends show high regeneration capacity while retaining good flux ranges. The membranes prepared by this process exhibit good separation characteristics and provide an improved membrane with enhanced qualities over prior art membranes. |
