The surface of poly(ether imide) membranes was functionalized with linear, methylated oligoglycerols with M—n = 1120, 1800, and 2270 g· mol−1, and the protein adsorption as well as platelet adhesion were investigated. The oligoglycerols had a higher stability to oxidation than OEG and resisted protein and platelet adhesion equally well as poly(ether imide) surfaces functionalized with monomethoxy oligo(ethylene glycol) (M—n = 1320 g· mol−1).
