“…In the studied range of molecular masses (6000-131600), almost a twofold increase in particle size is observed. As is known, the complexes of this type may be formed with the involvement of one polyelectrolyte chain [2,7,15] or a great many macromolecules (up to 40-50) [3,15]. For comparison of the sizes of PESC particles and PAMAC macromolecules, the average unperturbed sizes of macromolecular coils, , were calculated.…”

The formation of polyelectrolyte-surfactant complexes of poly(N,N diallyl N,N dimethylam monium chloride) of various molecular masses with sodium dodecylsulfate has been studied with the use of turbidity titration and laser diffraction-scattering. It has been shown that the molecular mass of the polyca tion has a significant influence on the boundary compositions of the system, which are related to the appear ance of a complex phase, and on the particle size of the complex.

“…The experiments were performed using LCsolution software; the obtained results were subsequently processed by the GPC-Postrun Analysis program. Dynamic light scattering (DLS) and static light scattering (SLS) are very efficient in the analysis of molecular characteristics of polymers, PECs and IPECs [8,[14][15][16][17][18][19][20]. The "PhotoCor-Complex" setup (Photocor Instruments Inc., Moscow, Russia) was used in light scattering experiments; the spectrometer was equipped with a real-time correlator (288 channels, 10 ns).…”

“…After reaching stoichiometric composition of a complex, the ζ-potential of PEC dispersions decreases, thus leading to the formation of a precipitate [8,9]; however, if the total concentration of PEC in the dispersion is lowered, precipitation can be avoided at stoichiometric ratio of the components [10].…”

In the present work, we suggest a novel method for obtaining interpolyelectrolyte complex (IPEC) by free radical polymerization in water-salt dispersions of polyelectrolyte complexes (PECs) based on an anionic polyelectrolyte (sodium salt of poly (2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS-Na)) and a cationic surfactant ((11-acryloyloxy) undecyl)-trimethylammonium bromide (AUTAB), as well as on PAUTAB cationic comblike polyelectrolyte and AMPS-Na monomer. IPEC consisting of PAMPS and PAUTAB was obtained by two ways. The first one is polymerization of surface active monomers AUTAB in the presence of PAMPS, and the second one is polymerization of AMPS monomers in the presence of PAUTAB. Molecular hydrodynamics methods were used to determine the molecular properties of initial components, polyelectrolyte complexes (PECs), and IPECs. Analysis of the dependence between translational friction coefficient of macromolecules and their molecular masses (which takes into account excluded-volume effects) allowed us to determine the Kuhn segment length of PAMPS-Na macromolecule (A = 6 nm). Stable polyelectrolyte complexes, PEC, (PAMPS-AUTAB and PAUTAB-AMPS) were obtained by mixing solutions of components at low concentrations in equimolar ratios; polymerization of their low molecular weight components was carried out for the purpose of preparing IPECs. Comparison between scattered light intensity distributions measured for PEC and IPEC demonstrated that in IPEC solutions, only large aggregates of complex molecules are present, while in PEC solutions, two peaks were observed (those corresponding to diffusion of individual PECs and their aggregates). When concentrations of PEC components exceed 3.4 mM, polymerization results in the formation of IPEC precipitate which was studied by small angle X-ray scattering. It was found that the IPEC based on PAMPS-Na forms a film with hexagonal packing, and the PAUTAB-based IPEC forms a lamellar film.

“…Dynamic light scattering has proven reliable in the investigations of polymers, biopolymers, and complex self-organizing systems [23][24][25][26]. The data obtained by this method include distribution of relaxation times corresponding to different mechanisms involved in the motion of components of a molecular system [27,28].…”

Polymerizable surfactants now attract a great interest due to high potential of their practical application as components of pseudostationary phase in micellar chromatography, drug carriers, and "building blocks" for molecular design of nanoparticles and nanostructured polymer materials, for encapsulation of various biological preparations. In the present work, we have studied poly(N-acryloyl-11-aminoundecanoic acid) (cross-linked comb-like polymer). Cross-linked polymers were obtained via copolymerization of the surfactant bearing double bond in hydrophobic tail with hydrophobic bifunctional cross-linker in micellar solution. Of special interest was the comparison between cross-linked and non-cross-linked polymers and influence of alkaline medium on characteristics of these samples. Non-cross-linked polymers were obtained by hydrolysis of the cross-linked product (treating with NaOH). The mixture of cyclohexanol and dioxane (1:1 volume ratio) was used as a solvent. Detailed studies of the obtained polymers by viscometry, dynamic light scattering, flow birefringence, and equilibrium and nonequilibrium electric birefringence were performed. It was established that during cross-linking process, two types of bonds are formed (the ones inside individual molecules and between several polymer chains). It was shown that crosslinked macromolecular nanoparticles can be transformed into comb-like polymers.
