Preparation of monodisperse polymer particles from 4-vinylpyridine

Dispersion polymerization of 4‐vinylpyridine was performed by using polystyrene‐block‐polybutadiene as stabilizer in a mixture of N,N‐dimethylformamide (DMF) and toluene to produce polymer particles. The weight ratio of the solvents affects the particle size and dispersity. In the range of DMF conte...

Zusammenfassung:Dispersion polymerization of 4‐vinylpyridine was performed by using polystyrene‐block‐polybutadiene as stabilizer in a mixture of N,N‐dimethylformamide (DMF) and toluene to produce polymer particles. The weight ratio of the solvents affects the particle size and dispersity. In the range of DMF content from 5 to 20 wt.‐%, uniform particles of a diameter of ca. 1 μm were obtained. The present system was expanded to the preparation of monodisperse particles of poly[(4‐vinylpyridine)‐co‐(methacrylic acid)].
