Interpolyelectrolyte Complexes of Amphiphilic Polymers: The Case when a Synthesis Sequence Affects Properties

The feasibility is considered of targeted production of interpolyelectrolyte complexes (IPECs) with an ordered supramolecular structure by polymerization in the composition of various polyelectrolyte–colloid complexes, direct mixing of polyelectrolytes in solution, and an interfacial reaction of polyelectrolytes. Using scanning electron microscopy and small-angle X-ray scattering, differences in the structure of interpolyelectrolyte complexes due to synthesis have been demonstrated. Methods for synthesizing IPEC dispersions with a controlled particle radius and the stability of such dispersions to dissociation into individual components are discussed, as well as some practical aspects of their use including laboratory testing of application potential.
