Claim 0:
1. Membranes for liquid treatment, comprised at least predominantly of multiblock copolymers of the general formula (1), where
X=connection point
E=C2 to C4 alkyl ether
A=other block component not containing silicone
R=C1 to C4 alkyl radical and/or phenyl radical
m=1<m<500
n=0≤n<100
o=1<o<10
p=1<p<10
z=1<z<25,
the molar ratio of the silicone-containing block component and the other block component A in the multiblock copolymer is between 5:1 and 1:5, wherein
the silicon-containing block components are predominately arranged at the surface of the membranes, and
the membranes have a pore size of 1 nm to 1 μm.
