摘要: The present invention relates to porous polymers comprising a perfluoropolyether unit, to a process for producing such porous polymers, in particular to a process for polymerising or copolymerising monomers incorporating perfluoropolyethers to form porous polymers, to articles made of or comprising porous polymers comprising a perfluoropolyether unit, such as membranes or ophthalmic devices, and to the use of porous polymers comprising perfluoropolyether units as articles, such as membranes or ophthalmic devices. The perfluoropolyether units are preferably of the formula (PFPE):--OCH.sub.2 CF.sub.2 O(CF.sub.2 CF.sub.2 O).sub.x (CF.sub.2 O).sub.y CF.sub.2 CH.sub.2 O-- wherein the CF.sub.2 CF.sub.2 O and CF.sub.2 O units may be randomly distributed or distributed as blocks throughout the chain and wherein x and y may be the same or different such that the molecular weight of the perfluorinated polyether is in the range of from 242 to 4,000. The porous polymers comprising one or more perfluoropolyether units having a water content when fully swollen in water which is higher than that of the same polymer if polymerized under conventional conditions, and are suitable for application, e.g., as soft contact lenses.
