The present disclosure describes articles, such as medical articles, containing a substrate having disposed thereon a hydrophilic gel material (e.g., a shaped hydrophilic gel material or a coating of a hydrophilic gel material) and methods for making such articles. Methods are provided for making hydropliilic gel materials from a precursor composition that contains a polar solvent and a polymerizable material that is miscible with the polar solvent.
L'invention concerne des articles, tels que des articles médicaux, contenant un substrat sur lequel est disposé un matériau de gel hydrophile (par exemple un matériau de gel hydrophile mis en forme ou un revêtement de matériau de gel hydrophile) et des procédés de préparation de tels articles. Des procédés de préparation de matériaux de gel hydrophiles à partir d'une composition de précurseur qui contient un solvant polaire et un matériau polymérisable qui est miscible avec le solvant polaire sont proposés.
