ABSTRACT:
This invention concerns a method of immobilizing a polymer hydrogel on the surface of a corresponding polymer substrate, and a polymer substrate that has a polymer hydrogel layer immobilized, at least in areas, on its surface. The invention has applications particularly as a biocompatible hydrogel coating in the field of medical technology, for example as a coating for surfaces coming in contact with blood, as in hemodialysis, and as a coating for urinary catheters, venous catheters, stents and other surfaces.
