MODIFICATION OF SURFACES OF POLYMERIC ARTICLES BY MICHAEL ADDITION REACTION

摘要

A medical device having an increased surface hydrophilicity comprises a coating polymer comprising units of a polymerizable hydrophilic compound that is attached to the surface of the medical device via the Michael addition reaction. The coating polymer can be applied to a medical device comprising a hydrogel material. The attachment of the coating polymer may be enhanced by increasing the population of the medical-device surface functional groups before contacting the medical device with the coating polymer.
