A semipermeable composite membrane, a process for the manufacture thereof, as well as application of such membranes for the separation of components in an organic liquid phase or in the vapour phase

摘要

Semipermeable composite membrane, with a porous carrier substrate, whereby said carrier substrate is provided with a polymer network obtained by polycondensation, especially interfacial polymerisation, which is built up of at least one reactive polyfunctional monomer or oligomer or prepolymer or polymer, and at least one acid halide containing polymer.;The specialty of this semi-permeable composite membrane consists therein that the acid halide containing polymere itself is built up of one or more vinyl containing monomers.;The acid halide containing polymer is generally a copolymer of acryoylchloride H₂C=CHCOCl or methacryloyl chloride H₂C=C(CHl3)COCl with one or more vinyl containing monomers.;Usually the vinyl containing monomer is an acrylate or an acrylamide or a mixture thereof.;The invention further relates to a process for the manufacture of such membranes, as well as a method for the separation of components in an organic liquid phase or in the vapour face using a semipermeable composite membrane according to the invention.
