A method of preparing a hydrophilic hybrid silicone polymer includes combining (a) a silicone having one or more reactive or polymerizable groups and (b) at least one hydrophilic monomer in the presence of (c) at least one initiator to form a mixture. The method further includes polymerizing the mixture to form the hydrophilic hybrid silicone polymer. L'invention concerne un procédé de préparation d'un polymère de silicone hybride hydrophile qui comprend la combinaison de (a) une silicone ayant un ou plusieurs groupes réactifs ou polymérisables et (b) au moins un monomère hydrophile en présence de (c) au moins un initiateur pour former un mélange. Le procédé comprend en outre la polymérisation du mélange pour former le polymère de silicone hybride hydrophile.
