Zusammenfassung:	PCT No. PCT/EP97/01409 Sec. 371 Date May 10, 1999 Sec. 102(e) Date May 10, 1999 PCT Filed Mar. 20, 1997 PCT Pub. No. WO97/35905 PCT Pub. Date Oct. 2, 1997The invention is directed to a process for producing a porous polymer comprising the steps of: (1) dispersing a porogen in a continuous monomer component phase wherein said continuous monomer component phase comprises at least one monomer having at least one perfluoropolyether unit and wherein said porogen is an optionally substituted poly(alkylene)glycol; (2) thereafter polymerising the continuous monomer phase; and (3) removing the porogen from the porous polymer.
