Abstract: front page image
(EN) Disclosed are: a polymer for treating the surface of a medical device such as a contact lens to suppress the reduction in lubricity of the device even when the device is scrubbed; a medical device having the polymer on the surface so that the reduction in lubricity over time is suppressed; and a wetting agent containing the polymer. The polymer for treating the surface is a copolymer which is water-soluble and includes as constitutional units the following monomers A and B: monomer A: a monomer containing a (meth)acryloyl group and an ester or amide structure in a molecule, in which the ester or amide structure is not constituted by including a part of the (meth)acryloyl group; monomer B: a monomer containing a (meth)acrylamide group in a molecule and having a structure different from that of the monomer A.
(FR) L'invention concerne un polymère destiné au traitement de surface empêchant la réduction du caractère glissant d'un dispositif médical tel qu'une lentille de contact même après avoir été nettoyé et lavé; un dispositif médical présentant le polymère sur sa surface et ayant une réduction inhibée du caractère glissant au fil du temps; et un agent mouillant contenant le polymère. Le polymère destiné au traitement de surface est un copolymère soluble dans l'eau contenant un monomère (A) et un monomère (B) en tant qu'unité structurale. Le monomère (A) a un groupe (méth)acryloyle, et une structure ester ou une structure amide, dans la molécule, la structure ester et la structure amide ne contenant pas de parties du groupe (méth)acryloyle. Le monomère (B) a un groupe amide (méth)acrylique dans la molécule, et a une structure différente de celle du monomère (A).
