Radikaltransportprozesse bei der Emulsionspolymerisation. II. Bestimmung kinetischer Parameter bei der Polymerisation von Vinylchlorid

Abstract: Ein neues kinetisches Modell der Emulsionspolymerisation bei Ablauf von Radikaldesorptionen und -reabsorptionen wird mit anderen aus der Literatur bekannten Bruttogeschwindigkeitsmodellen fur Vinylchlorid als Monomer verglichen. Dabei hat das Wachstum der desorbierenden Kettenubertragerradikale fur die Polymerisationskinetik besondere Bedeutung. Durch Anpassung an experimentelle Ergebnisse werden u. a. der Einfangspolymerisationsgrad und der mittlere Diffusionskoeffizient in den Teilchen sowie die Konzentratio… Show more

However, many experimental data suggest that the average degree of polymerization varies strongly with the conversion 8) .…”
