Abstract
The invention concerns the field of polymer chemistry and relates to membranes, such as those that can be used, for example, for the preparation of aqueous solutions using microfiltration or ultrafiltration. The object of the present invention is to specify membranes which have improved anti-fouling properties and sliding friction properties. The object is attained with membranes comprised at least predominantly of multiblock copolymers of the general formula (1) where
