The formation of mixed aggregates in the solution containing dimethylaminomethylated resorcinarene and polyetheleimine (PEI) has been shown by the methods of tensiometry, conductometry, dynamic and electrophoretic light scattering. The values of the critical aggregation concentration and their zeta potential were determined. It has been established that the addition of PEI to the resorcinarene solution does not lead to formation of hydrophobic domains capable of solubilizing big organic molecules. The isoelectric point in the mixed system is observed at low concentrations of the macrocycle confirming the electrostatic interaction between the protonated amino groups of the polymer and the lower rim of resorcinarene.
