Studies on the Kinetics of Acryl amide Polymerization Redox Initiated by Diperiodato-argentate(Ⅲ) Complex Ion

Abstract

Abstract: The kinetics of acrylamide polymerization initiated by diperiodato-argentate(Ⅲ)[Ag (Ⅲ) was studied in alkaline medium.The results indicate that the equation of the polymerization rate is as follows:R_p=k[AM]^1.21[Ag(Ⅲ)]^0.90 and the overall activation energies of AM polymerization are 48.5kJ/mol.The polymer molecular weight decreases with increasing Ag(Ⅲ).The effects of reaction conditions on the polymerization rate were also studied.The initiation mechanism was proposed.

Key words: Diperiodato-argentate(Ⅲ), Acrylamide, Redox initiation
