Abstract

Membrane semi-perméable de filtration n'adsorbant sensiblement par les protéines. La membre est préparée d'une solution à couler comprenant un prépolymère copolymérisable lors d'un contact avec un liquide coagulant, un polymère ne pouvant réagir facilement avec le prépolymère et qui est sensiblement insoluble dans le liquide coagulant et un solvant. L'invention s'applique notamment aux membranes de filtration, d'ultrafiltration et de microfiltration.
