Abstract
Multifunctional crosslinkers are a reaction product between a polyaziridine compound and two or more functionalized benzophenones. The polyaziridine compound is linked to the functionalized benzophenones through two or more reacted aziridine groups. Coating compositions, comprising: a polymer, and multifunctional crosslinkers. Coated medical devices, comprise a lubricious coating bonded adjacent to an exterior surface of the medical device. The lubricious coating is prepared by UV-curing a coating composition, wherein the coating composition comprises: a water/isopropyl alcohol (IPA) soluble polymer and/or a UV-curable polymer, and a water/IPA soluble multifunctional crosslinker.
Claims8
