Abstract
Semipermeable films useful as dialysis membranes are prepared from starch-based composites. The films are shaped by conventional methods from a plasticized matrix comprising highly gelatinized starch and ethylene acrylic acid copolymer neutralized with a strong alkali. These films are remarkably transparent and resistant to degradation in the presence of aqueous solutions.
