✦ Synopsis


The kinetics of emulsion polymerization of vinyl acetate using the redox system potassium persulfateacetone sodium bisulfite as initiator is studied. The effect of the reaction conditions on the rate of polymerization and on the number and size of the formed particles is established. The polymerization proceeded smoothly till high conversion and yielded stable emulsions. The apparent activation energy for the polymerization system has been calculated.

Untersuchungen zur Emulsionspolymerisation von Vinylacetat

Die Kinetik der Emulsionspolymerisation von Vinylacetat bei Initiierung mit einem Redoxsystem aus Kaliumpersulfat und Acetonnatriumbisulfit wurde untersucht. Der EinfluB der Reaktionsbedingungen auf die Polymerisationsgeschwiridigkeit sowie die Anzahl und GroBe der gebildeten Teilchen wurde ermittelt. Die Polymerisation verlief stetig bis zu hohem Umsatz und ergab stabile Emulsionen. Die scheinbare Aktivierungsenergie dieses Polymerisationssystems wurde berechnet.
