Abstract
A process for the surface functionalization of a polymeric substrate, which process comprises: a) contacting the substrate with a diarylcarbene precursor, b) generating a carbene reactive intermediate from the diarylcarbene precursor so that it reacts with the substrate to functionalize the surface, and c) further functionalizing the activated substrate obtained in step (b).
