Abstract : A series of surface-active, functionalized anilines were polymerized at fluid interfaces. By carefully maintaining isobaric conditions, kinetic and derived thermodynamic activation parameters were determined. The substitution position of the alkyl moiety on the aniline ring and the applied surface pressure was found to strongly influence the kinetics. Further analysis allowed a two rate constant model to be developed. The experiments were also extended to the polymerization of thin films at a planar liquid/liquid interface.
