Abstract
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 hydrophilic gel materials from a precursor composition that contains a polar solvent and a polymerizable material that is miscible with the polar solvent.
