A rotary filtration device having at least two members, one at least partially within the other to define a fluid gap therebetween, is disclosed. One or more filters are located on one or more of the members facing the fluid gap. Sufficient uncharged hydrophilic polar groups, preferably uncharged substituted amide groups, are located on the surface of the filter to render the surface hydrophilic.

Cross-linked polymeric gels or films are prepared by dissolving in a suitable solvent a linear polymer or polymers containing pendant amidocarbonyl or oxycarbonyl groups, hydroxyl groups present as either pendant groups from the polymer or as a low molecular weight polyol, and a strongly acidic catalyst (which may also be a pendant group on a polymer). The solvent is removed by coagulation and/or drying and the dry material is heat-cured, thus cross-linking and insolubilizing the polymer or polymers.
