PROCESS FOR MODIFIYING SURFACES USING THE REACTION PRODUCT OF A WATER-INSOLUBLE POLYMER AND A POLYALKLENE IMINE

摘要

A process for modifying a surface of an article that includes treating a surface with a solution that includes an organic solvent, and the reaction product of a substantially water insoluble polymer and a polyalkylene imine to form a modified surface. Additionally, a biologically active agent such as an anti-thrombotic agent may be attached to the modified surface.
