The kinetics of aqueous polymerization of acrylamide and methacrylamide using the redox pair potassium permanganate and malonic acid was studied. It was found that the order of the polymerization reaction is 0.5 with respect to permanganate and malonic acid, respectively, and 1.0 with respect to the concentration of the monomers. Polymer samples were prepared under different conditions, and their viscosity average molecular weights were determined. A plausible mechanism for the explanation of the experimental results is proposed.
The aqueous polymerization of methacrylamide was studied by using persulphatel malic acid and persulphate/ethanolamine redox pairs under nitrogen atmosphere.The order with respect to persulphate was found to be one half with both the redox systems. Malic acid and ethanolamine show half order and zero order, respectively. Methacrylamide has first order dependence on the rate of polymerization initiated by K,&Q-malic acid system and one and half order dependance on the rate of polymerization initiated by K,&Q -ethanolamine redox pair. Viscometric average molecular weight was determined for the samples obtained under different kinetic conditions.
ZUSAMMENFASSUNG:Die Polymerisation von Methacrylamid wurde in wabriger Phase unter Verwendung von Persulfat/Apfelsaure und Persulfat/Ethanolamin als Redox-Systeme unter Stickstoff untersucht. Bezuglich des Persulfats wurde fiir beide Falle eine Reaktion erster Ordnung gefunden, fur ApfelsBure ergab sich die Ordnung 1/2, fur Ethanolamin nullte Ordnung. Fur Methacrylamid wurde im Ansatz mit K,&Q/b;pfelsaure erste Ordnung und im Ansatz mit K,&Q/Ethanolarnin die Ordnung 1,5 gefunden. Das mittlere Molekulargewicht wurde viskosimetrisch fur die unter verschiedenen Bedingungen erhaltenen Proben bestimmt.
