“…An advantage of this method is the relatively high heat transfer out of the reacting monomer droplets. Many factors affect the particle size distribution produced in suspension polymerization, e. g. the concentration of stabilizer [3,4,[7][8][9]11, 171, the hold-up fraction [4,9,13, 171 and the geometry [12,13,171, the size [3-6, 8, 141 and the speed of the impeller [3-8, 12, 13, 15, 171. Even though some researchers [l] assumed that the particle sizes are determined at the beginning of the experiment, before a noticeable conversion can take place, Langner et al [15] showed that these sizes change during the overall polymerization process.…”
