<jats:title>Abstract</jats:title><jats:p>In contrast to other plasma modification processes of polymer surfaces, the bromination is very selective and shows a high yield in CBr groups. The most convenient bromination process was found using bromoform, which was thus preferred to elemental bromine, allyl bromide, vinyl bromide or <jats:italic>tert</jats:italic>‐butylbromide. The bromoform process give yields in CBr up to 40 CBr or more, with only 2–3% co‐introduction of O‐functionalities whereas allyl bromide results in yields of about 20 CBr and more, but in more than 10% oxygen‐containing by‐products. CBr groups serve as anchoring points for grafting of molecules, oligomers and pre‐polymers of diole or diamine character.</jats:p>
