摘要： The present invention is directed toward the renewable surface treatment of medical devices such as contact lenses and medical implants. In particular, the present invention is directed to a method of modifying the surface of a medical device to increase its biocompatibility or hydrophilicity by coating the device with a removable hydrophilic polymer by means of reaction between reactive functionalities on the hydrophilic polymer which functionalities are complementary to reactive functionalities on or near the surface of the medical device at reaction temperatures of less than about 55 °c.

摘要： Nouvelle classe de tensioactifs polymérisables décrits par la formule (DC[AxBy], permettant de modifier les surfaces d'objets polymères. Dans la formule, A représente au moins un monomère hydrophyle à insaturation éthylénique, B représente au moins un monomère hydrophobe à insaturation éthylénique, D est un groupe terminal à insaturation éthylénique, y est compris entre environ 0,1 et environ 0,9 et x + y = 1. On décrit également des précurseurs copolymères non orientés de ces tensioactifs polymérisables.
