| Abstract: | 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)]. |
