PCT No. PCT/DE93/00347 Sec. 371 Date Dec. 20, 1994 Sec. 102(e) Date Dec. 20, 1994 PCT Filed Apr. 21, 1993 PCT Pub. No. WO93/20930 PCT Pub. Date Oct. 28, 1993A membrane comprised of a graft copolymer includes a base component and a copolymer component. The base component includes a first polymer with a repeating unit: wherein m=0.1-0.9, n=0.9-0.1, p=0.03-0.04, R1 can be a linear, branched or cyclic C1-C12 hydrocarbon radical, R2 can be a linear, branched or cyclic C1-C12 hydrocarbon radical, and at least one of R1 and R2 is a linear or branched hydrocarbon radical with a terminal C=C double bond. The base component can include a second polymer with C=C double bonds located in the main chain and/or a side chain. The second polymer has a repeating unit: wherein m=n; R1 and R2 are identical or different; and 10 to 100% of R1 and/or R2 have a C=C double bond.
