Abstract
The 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.
