ABSTRACT:
A semi-permeable composite with a porous substrate having a polymer network obtained by interfacial polymerization of a reactive polyfunctional monomer having reactive groups --NHR. (R.sub.1 is H or a C.sub.1 -C.sub.20 alkyl groups), --OH or --SH and a reactive polyfunctional material having --NCO reactive groups built from a polyalkylene oxide with terminal --OH groups and a polyisocyanate, and a process for separating components in an organic liquid medium by using said composite.
