The methods and compounds disclosed herein relate to the surface modification of UHMWPs by means of a catalytic C—H bond insertion catalyst using a rhodium catalysts in conjunction with carbene-generating diazo compounds. The catalytic treatment imparts covalently added functionality to the UHMWPE surface. This functionality acts as an excellent grafting mechanism for grafting, bonding, or adhering further materials to the UHMWPs surface.
