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)].
