The present invention relates to a porous polymer containing perfluoropolyether units, a method for producing such a polymer, particularly for polymerizing or copolymerizing a monomer containing perfluoroether to form a porous polymer. The invention relates to the use of a porous polymer comprising perfluoroether units as a product produced or comprising perfluoroether units, for example membranes or ophthalmic devices and products such as membranes or ophthalmic devices. Perfluoroether units, preferably formula (PFPE): - OCH 2 CF 2 O (CF 2 CF 2 O) x (CF 2 O) y CF 2 CH 2 O- ( wherein, CF 2 CF 2 O and CF The 2 O units can be randomly distributed throughout the chain or distributed as blocks and x and y are such that the molecular weight of the polyperfluorinated polyether ranges from 242 to 4,000. Can be the same or different). A porous polymer comprising one or more perfluoropolyether units having a water content, when swollen sufficiently in water, higher than that of the same polymer polymerized under normal conditions. |
