Composite membranes of poly(methyl methacrylate) blends |
abstract |
Composite membranes are disclosed having a separation layer comprised of a mixture of poly(methyl nmethacrylate) nor a copolymer thereof and at least one cellulosic derivative resulting in enhanced separation and permeating ncharacterisÂntics of the overall composite membrane. Processes for making these composite membranes and the methods of nusing them nare also disclosed. The membranes are particularly useful in gas separation applications and are most suited for nthe separÂnation of hydrogen from a hydrogen containing stream. |
