Although the previously known processes for the preparation of styrene polymers by suspension polymerisation allow a certain amount of control of the particle size, the distribution curve is, however, always relatively broad, i.e. the proportion of oversize and/or undersize particles is still too high. It is proposed to add from 50 to 500 ppm, based on the aqueous phase, of carbonates or bica...
