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 tert ‐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.
