✦ Synopsis
The initiation of acrylamide polymerisation in aqueous media with a redox system of the type F S + /organic complex of Fe(III)/Na&O, was studied. Several carboxylated amines containing the iminodiacetate group as a basic structural unit were used as complex forming reagents. A direct relation between complex stability and initiation efficiency was found. The polymerisation kinetics were studied with the most effective initiating system. Several kinetic parameters were determined and an essential relationship between polymerisation behaviour, polymer characteristics and component ratio of the initiation and polymerisation system was found. An attempt was made to explain these results.
