Popis:	The adsorption on silica of diblock copolymers of styrene and 2-vinylpyridine with large pyridine blocks from toluene solutions at concentrations below the cmc was investigated by using radiolabeled polymers. Fast adsorption was observed for initial adsorption on bare silica, which became fully covered by chain segments of pyridine blocks. A slow rearrangement of the interfacial layer then followed, the surface relaxation being faster for copolymers with larger pyridine blocks
