Abstract

The aggregation in aqueous systems of hydrophobically modified poly(ethylene imines) and their mixtures with cationic surfactants, as well as the catalytic activity of these compositions in the hydrolysis of O-4-nitrophenyl-O-ethylchloromethylphosphonate, are studied by conductometry, tensiometry, light-scattering, and viscometry methods. Critical association concentration, hydrodynamic radii of polymer and polymer-colloid aggregates formed in such systems, as well as kinetic parameters of hydrolysis are determined.
