Microparticles of Polyelectrolyte Complexes Based on Poly-N,N-Diallyl-N,N-Dimethylammonium Chloride Modified with Some Amino Acids

The formation of microparticles composed of copolymers of N,N-diallyl-N,N-dimethylammonium chloride and N,N-diallyl-N,N-dimethylammonium hydroxide modified with leucine, alanine, and valine is studied in the presence of sodium dodecyl sulfate as a micelle-forming ionogenic surfactant. It is shown that the lyophilizing ability of polyelectrolytes and, accordingly, the size of the microparticles, depend on the degree of functionalization of the polymer. The conditions for the preparation of complex systems are optimized for resistance to aggregation and to obtain the desired particle size.
