Abstract

The polymerization of acrylamide (AA) initiated by 4,4'-azobis (4- cyano pentanol) (ACP) was investigated in aqueous solution at 60-degrees-C. The molecular weight and the conversion depend on polymerization duration and initiator concentration. Polymerization of AA initiated by ACP yields polyacrylamide (PAA) with hydroxyl terminal groups. Redox polymerization of AA initiated by hydroxyl terminated PAA in conjunction with Ce(IV) provided increase in the molecular weight of the initial polymer.
