摘要：

The kinetics of adsorption of diblock copolymers of poly(2-vinylpyridine) and polystyrene from toluene solutions on silica was investigated by using radiolabeled polymers. To study the relaxation of the anchoring block, only copolymers with a large pyridine block was selected. Adsorption was performed from solutions at concentrations below the cmc. 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.
