Abstract: The kinetics of acrylamide polymerization in water initiated by (NH₄)₂S₂O₈ was studied in presence of the surfactants C₈H₁₇S0₃Na, C₁₂H₂₅S0₄Na, and C₁₆H₃₃S0₄Na. In the presence of the surfactants an increase in the acrylamide polymerization rate and decrease in the degree of polymerization was obser­ved. At concentrations above critical micellar concentration the surfactant  C₁₂H₂₅S0₄Na, causes a gentle decrease of the overall activation energy of acrylamide polymerization. The length of the n-alkyl chain in the surfactant molecule does not influence the acrylamide polymerization rate.
