Abstract
Terpolymers of dimethyldiallylammonium chloride, methyldodecylbenzyldiallylammonium chloride and sulfur dioxide were synthesized. Aromatic substitution reactions of dinitrochlorobenzene with OH− (an ion—molecule reaction) and of dinitrofluorobenzene with aniline (a molecule—molecule reaction) were studied in the presence of the terpolymers. These two reactions were accelerated by the polymers: the ion—molecule reaction was accelerated more appreciably than the molecule—molecule reaction. The rate-enhancing effect became larger with an increasing content of dodecyl group. The addition of ethanol decreased the acceleration. The acceleration observed was due to a decrease in the activation enthalpy.
