Abstract

Una membrana permselettiva costituita da una composizione di amido e di un polimero sintetico termoplastico in cui amido e polimero sintetico formano una struttura almeno in parte interpenetrata a livello molecolare è utilizzata per la separazione mediante pervaporazione di miscele idroorganiche liquide.
