Claims43
An orthopedic implant comprising a crosslinked ionic polymer that comprises sulfonic-acid-derivatized groups, wherein the sulfonic-acid-derivatized groups are present at a surface of the crosslinked ionic polymer and extend from the surface into a bulk of the crosslinked ionic polymer by a distance of at least 500 microns, and the crosslinked ionic polymer has a thickness of up to 10 mm.
An interpenetrating or semi-interpenetrating polymer network that comprises a first polymeric network comprising a first polymer and a second polymeric network comprising a crosslinked ionic polymer that comprises sulfonic-acid-derivatized groups, wherein the sulfonic-acid-derivatized groups are present at a surface of the interpenetrating or semi-interpenetrating polymer network and extend into the interpenetrating or semi-interpenetrating polymer network by a distance of at least 500 microns, and the interpenetrating or semi-interpenetrating polymer network has a thickness of up to 10 mm.
