摘要：

The polymerization of acrylamide (AAm) initiated by polyazoesters (PAE) possessing poly(ethylene glycol) (PEG) segments and azo functions was investigated in aqueous solution at 70-degrees-C. Polymerization of AAm initiated by PAE yields polymers with PEG segments and appropriate hydroxy functions for the subsequent redox polymerization. Polymerization of AAm induced by these polymers in conjunction with Ce(IV) provided increase in the molecular weight of the initial polymer without formation of insoluble polymer. The water-soluble polymers obtained at various stages were tested in the flocculation of suspension of tincal concentrate and showed good flocculating properties.
