What is Adsorption of Poly-N-Ethyl-4-Vinylpyridinium Bromide on the Surface of Carboxylated Latex Particles: Composition and Structure of Interfacial Complex about?

similar in many respects to the interaction of oppositely Interaction between poly-N-ethyl-4-vinylpyridinium bromide charged linear polyions (14,15). Hence, when describing and polystyrene latex particles, the surface of which is covered the adsorption of polyelectrolytes on oppositely charged colwith methacrylic acid-polystyrene copolymer, was studied. The loid species, both of these factors should be taken into acpolycation adsorption on the particle surface was found to be a count. ## cooperative process which is accompanied by interface interpoly- The main goal of our work is to assess the contribution electrolyte complex formation and neutralization of the surface of each of the factors to the composition and structure of charge. In the adsorbed macromolecules, about 75% of the polythe polyelectrolyte-colloid complex, using poly-N-ethyl-4cation units form ionic contacts with negatively charged groups vinylpyridinium bromide and carboxylated polystyrene latex of the latex surface. In the presence of the excess polycation, the surface charge become positive, which results in termination of particles. the polycation adsorption.
