Abstract
Abstract A mixture of at least one non-sulphonated polysulphone and at least one sulphonated polysulphone, this mixture consisting of 10 to 30% by weight of a sulphonated polysulphone which has a theoretical exchange capacity of from 500 to 1,200 meq/kg is provided. Such mixtures enable one to obtain semi-permeable membranes using relatively concentrated solutions of the mixtures. The resulting membranes are particularly suitable for use in ultrafiltration.
