The invention provides an actinically-crosslinkable linear polysiloxane copolymer. The actinically-crosslinkable polysiloxane copolymer can be used to prepare a silicone hdyrogel contact lens having a hydrophilic surface without post-curing surface treatment. The invention is also related to a silicone hydrogel contact lens obtained from a lens-forming material including an actinically-crosslinkable polysiloxane copolymer of the invention and to a method for making an actinically-crosslinkable polysiloxane copolymer of the invention. In addition, the invention provides a non-crosslinkable linear polysiloxane copolymer capable of being used as a internal wetting agent which can render the surface of a silicone hydrogel contact lens hydrophilic.
Linvention concerne un copolymère de polysiloxane linéaire actiniquement réticulable. Le copolymère de polysiloxane actiniquement réticulable peut être utilisé pour préparer une lentille de contact dhydrogel de silicone présentant une surface hydrophile, sans traitement de surface post-durcissement. Linvention concerne également une lentille de contact dhydrogel de silicone obtenue à partir dun matériau formant lentille renfermant un copolymère de polysiloxane actiniquement réticulable de linvention et un procédé destiné à fabriquer un copolymère de polysiloxane actiniquement réticulable de linvention. En outre, linvention concerne un copolymère de polysiloxane linéaire non réticulable susceptible dêtre utilisé en tant quagent mouillant interne susceptible de rendre la surface dune lentille de contact dhydrogel de silicone hydrophile.
