Özet

Polymerization of acrylamide was carried out with cerium(IV)-EDTA redox initiator system with and without electrolysis. The effect of temperature, time, cerium(IV), and EDTA concentrations on the polymerization yield and molecular weight were studied and compared with electrolytic conditions. At low concentrations of cerium(IV) the electrolytic method continuously supplying Ce(IV) from Ce(III) has an advantage over the nonelectrolytic method for which polymerization did not occur under these conditions. A possible polymerization mechanism is suggested.
