| Amphiphilic block copolymers based on poly-N-vinylpyrrolidone and polystyrene have been obtained by free radical polymerization. The synthesized samples of block copolymers differed in hydrophilic block content. The structure of the obtained copolymers was confirmed by IR and 1H NMR spectroscopy. Molecular weight and structural-conformational characteristics of the samples were determined by the methods of static and dynamic light scattering and viscometry in dilute chloroform solutions. Aggregates were fixed in the solution for the block copolymers containing poly- N -vinylpyrrolidone 65–71 mass.%. |
