Abstract
A new method is provided to impart a hydrophilic lubriciious coating onto articles such as medical devices. A device, for example a catheter, is first contacted with a polyisocyanate solution, to provide coupling, then contacted with a poly(carboxylic acid) solution to give a coating, and is then finally oven dried. These coatings have lubricity that only becomes manifest upon exposure to water ro body fluids, and moreover, are also long lasting and have good abrasion resistance. This combination of properties is not available from other currently used or proposed coatings.
