Abstract The aggregation and the catalytic properties of the systems based on the alkylated polyethyleneimine, cationic surfactants and calixarene in chloroform have been investigated by dielcometric titration and UV-spectrophotometry methods. The formed mixed aggregates accelerate the process of the interaction of polymer with 4-nitrophenyl-bis(chloromethyl)phosphinate. The catalytic effect depends on the surfactant concentration, the structure of surfactant and the presence of calixarene in solution.
Keywords: dielcometric titration, UV-spectrophotometry, supramolecular catalytic systems, polyethyleneimine, aggregation and the catalytic properties
