Zur kenntnis der perlpolymerisation. 2. Mitt. praktische anwendung der dimensionsanalyse auf das system MMA – mowiol 70/88

Abstract: Die Perlpolymerisation von Methylmethacrylat in Gegenwart von Mowiol 70/88 bei Mowiolkonzentrationen über 10 g/l wurde untersucht. Mit Hilfe der Dimensionsanalyse konnte eine Gleichung für die Abhängigkeit der Perlgrößxe von den Versuchsvariablen aufgestellt werden. Versuche mit andern Schutzkolloiden bestätigten die durch diese Gleichung vorausgesagte Grenzflächenspannungsabhängigkeit. Die Bedeutung der einzelnen Kräfte für die Erhaltung oder Verringerung der Perlgröße konnte ermittelt werden.

“…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.…”
