Abstract: The cross-linked silicone polymer based material comprises a cross-linked silicone polymer matrix and photoinitiator groupings dispersed and bound in the matrix. The use of this material in processes aiming at making the material hydrophilic greatly simplifies the processes and the resulting products have particularly interesting and advantageous characteristics. The invention is useful in the manufacture of contact lenses.

Abstract: This invention pertains to a process for the manufacture of a hydrophilic polymeric product, consisting in causing a material comprising a crosslinked silicone polymer matrix and photoinitiator groups dispersed and immobilized within the polymer matrix to swell in a swelling solution comprising a solvent for swelling the crosslinked silicone polymer of the matrix of the material, a photopolymerizable hydrophilic monomer and optionally a crosslinking agent and a proton- or electron-donating coinitiator compound, when the material comprises photoactivable photoinitiator groups and does not comprise proton- or electron-donating coinitiator groups causing the photopolymerizable hydrophilic monomer to diffuse into the swollen material, and polymerizing, by irradiation, the photopolymerizable hydrophilic monomer.
