Abstract
Thin film composite ultrafiltration membrane which possesses desirable properties or characteristics may be prepared by casting a solution of a polyelectrolyte complex on a microporous support to form a thin film of the polyelectrolyte complex on the surface of the supports. The thickness of the polyelectrolyte complex membrane will range from about 600 to about 3,000 .ANG.. This membrane may then be used for the separation of low molecular weight solutes such as, for example, the separation of glucose from sucrose and higher molecular weight sugars.
