Abstract

A process for the bioactive coating of the surface of substrates, which entails graft polymerizing at least one vinyl monomer of the formula (I):R—(A)a  (I)in which R is an olefinically unsaturated organic radical, having the valence a,A is a carboxyl group —COOH, sulfuric acid group —OSO2OH, sulfonic acid group —SO3H, phosphonic acid group —OPO(OH)2, phosphoric acid group —PO(OH)2, phosphorous acid group —OP(OH)2, phenolic hydroxyl group or a salt of one of these groups, anda is an integer of from 1 up to and including 6,under radiative induction or thermally on a substrate surface which his been treated beforehand with a macroinitiator having groups which form free radicals in side chains of the polymer framework; with the proviso that a vinyl monomer I in which A is the carboxyl group —COOH or a salt of the carboxyl group contains at least one further radical A having a different one of the definitions specified for A or is used together with at least one further monomer I in which A has a different one of the definitions specified for A. If desired, a crosslinker may also be used for the coating. The present invention …
