ABSTRACT:
Semi-permeable membranes are made from polyamides, especially N-alkoxyalkyl polyamides, and water-soluble polyvinyl alcohols. The membranes are preferably formed as fibers. The membranes can be made from compositions containing the polymer components and a di(lower alkyl) sulfoxide, e.g. dimethyl sulfoxide. The membranes may contain complex-forming metal components. The membranes are useful for separating chemicals from their mixtures by techniques using an aqueous liquid barrier and complex-forming metals, e.g. for the separation of aliphatically-unsaturated hydrocarbons such as ethylene from close-boiling hydrocarbons.
