<p>A membrane which can be used in membrane filtration processes and which has a reduced tendency to fouling is a polysulphone or a plyether sulphone and a polyethylene oxide/polypropylene oxide substituted diamine and can be made by a phase inversion process in the presence of pore modifying agents such as an alcohol, glycerol or glycol to give a membrane which has a pore size of 0.1 ν to 1 micron and is hydrophilic.</p> |
