In order to introduce amine groups on poly(ethylene) (PE) surface, PE surfaces were preadsorbed with decylamine hydrochloride (DA.HCl) and subsequently treated with an argon plasma. It was shown by XPS (X-ray Photoelectron Spectroscopy), that approximately half of the preadsorbed (mono)layer was immobilized and that a substantial part (60-70%) of the incorporated nitrogen containing groups were amine groups. The availability of the surface amine groups for reactions was investigated by applying a gas phase reaction with 4-trifluoromethylbenzaldehyde and by a reductive methylation reaction in aqueous solution with 14C formaldehyde. A maximal number of reactive amine groups was found after a plasma treatment time of 2 s. The reductive methylation reaction was used to estimate the surface concentration of amine groups resulting in a typical surface concentration of 1 x 10(-6) mol/m2 after a plasma treatment time of 2 s.
