摘要： A purification method for a biological fluid comprising at least a filtration step through a membrane obtained from a sulfone polymer (PSI) derived from bio-based feed-stocks. In particular the polymer (PSI) comprises more than 50% moles recurring units (RPSI) comprising sugar moieties selected from the group consisting of those of formulae (E′-I) to (E′-III):
A membrane free from pore-forming agents comprising at least one sulfone polymer (PSI) and a method for preparing such a membrane.-

摘要： The invention relates to:—anion exchange blend membranes consisting the following blend components:—a halomethylated polymer (a polymer with —(CH2)x—CH2—Hal groups, Hal=F, Cl, Br, I; x=0-12), which is quaternised with a tertiary or a n-alkylated/n-arylated imidazole, an N-alkylated/N-arylated benzimidazole or an N-alkylated/N-arylated pyrazol to form an anion exchanger polymer. - an inert matrix polymer in which the anion exchange polymer is embedded and which is optionally covalently crosslinked with the halomethylated precursor of the anion exchanger polymer,—a polyethyleneglycol with epoxide or halomethyl terminal groups which are anchored by reacting with N—H-groups of the base matrix polymer using convalent cross-linking—optionally an acidic polymer which forms with the anion-exchanger polymer an ionic cross-linking (negative bound ions of the acidic polymer forming ionic cross-linking positions relative to the positive cations of the anion-exchanger polymer)—optionally a sulphonated polymer (polymer with sulphate groups —SO2Me, Me=any cation), which forms with the halomethyl groups of the halomethylated polymer convalent crosslinking bridges with sulfinate S-alkylation. The invention also relates to a method for producing said membranes, to the use of said membranes in electrochemical energy conversion processes (e.g. Redox-flow batteries and other flow batteries, PEM-electrolyses, membrane fuel cells), and in other membrane methods (e.g. electrodialysis, diffusion dialysis).

摘要： A membrane having a first outer surface having a plurality of pores in a skin layer and the plurality of pores having a closed perimeter in the skin layer. The membrane having a second outer surface and a porous supporting layer connecting the first outer surface to the second outer surface. The first outer surface of the membrane is a melt-fused skin layer from exposure to ultra-violet light.
