Abstract
Results of fundamental investigations in the intermacromolecular reactions and interpolymer complexes (IPC) to be performed by authors with co-workes within last 20 years have been intergrated and summarized in the present review. The raw of fundamental regularities in the effect of factors of different nature (pH, ionic strength, temperature, hydrophilic-hydrophobic balance of macrochain, etc.) on the complexation of nonionic polymers with polycarboxylic acids in aqueous solutions has been revealed. Critical pH upon complexation (pH crit. ) has been used for evaluation of the complexing ability of the polymers. It was shown tha tdepending on pH crit. all systems can be divided into 2 groups, namely, weak complexing and strongly complexing. The existence of two critical pH upon complexation reflecting the field of IPC and hydrophilic associations formation has been demonstrated by the method of luminescence spectroscopy.
