A PROCESS FOR PRODUCTION OF A SEMI-PERMEABLE MEMBRANE, A MEMBRANEMANUFACTURED BY SAID PROCESS AND THE USE OF SUCH A MEMBRANE FOR GAS OR LIQUID SEPARATION

摘要

A porous support material is selected having a relatively narrow pore size distribution. During a certain time one side of said support material is then exposed to a first chemical reaction partner. The other side of the support material is at the same time exposed to a second chemical reaction partner. In the penetrating pores or channels a chemical reaction takes place in a boundary region between the two reaction partners forming selectively occlusions blocking said pores and channels.
