“…The slope of linear dependence allows to obtain the Kuhn segment length A ¼ 62 Â 10 À8 cm, and hydrodynamic diameter d ¼ 34 Â 10 À8 cm was determined from the Y-axis intercept. The hydrodynamic diameter value for PAADA correlates with the structure of macromolecules far better than the value obtained earlier for PAAUA (d ¼ 45 Â 10 À8 cm) [29].…”

a b s t r a c tThe samples of poly(12-acryloylaminododecanoic acid) were synthesized in micellar solutions of the monomer. The possibility of obtaining polymeric ionogenic surfactants of different molecular masses by varying concentration of monomeric surfactant was demonstrated. Detailed studies of the obtained polymer were performed using macromolecular hydrodynamic methods, dynamic light scattering, scanning probe microscopy and flow birefringence. The parameter of equilibrium rigidity of macromolecules (the Kuhn segment length A ¼ 62 Â 10 À8 cm) and their effective hydrodynamic diameter were determined in mixed solvent (dioxane-cyclohexanol). Contributions made by optical microform and macroform effects to the observed dynamic birefringence were analyzed in detail. The intrinsic optical anisotropy of the monomer unit was estimated; it correlates well with the corresponding values for comb-shaped polymers of similar structure.

“…Recently we have published a number of papers concerning synthesis and studies of poly(11-acryloylaminoundecanoic acid) (PAAUA) and its cross-linked analogue in organic media [29]. It was found that these polymer chains possess rather high equilibrium rigidity (A z 10 nm).…”

“…Analogous results were obtained for the similar polymer (poly(N-acryloyl-12-aminododecanoic acid)), PAADA) [30]. It was also demonstrated that electric birefringence in solutions of comb-like polymer (PAAUA) occurs according to the deformation mechanism (at the expense of orientation of dipole moments of polymer side groups in electric field) [29]. It should be noted that in the absence of electric field, PAAUA molecules do not possess constant macromolecular dipole moment.…”

“…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]. Combination of this method with other techniques provides information about conformational and molecular mass characteristics of a system [29,30]. Anisotropy of optical polarizability of a monomer unit is a sensitive indicator of its structure; thus, it is successfully used for analysis of monomer unit structure.…”

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.

The rapidly increasing demand for lithium‐ion batteries and the fight against climate change call for novel materials that enhance performance, enable eco‐friendly processing, and are designed for efficient recycling. In lithium‐ion batteries, the binder polymer, used for cathode production, constitutes an integral but often overlooked component. The currently used polyvinylidene fluoride is processed with toxic organic solvents and has numerous other disadvantages concerning adhesion, conductivity, and recyclability. A change to aqueous processing using new, multi‐functional, purpose‐built materials that are soluble in water and fluorine‐free would thus constitute an important advance in the battery sector. Herein, four water‐soluble surfactant‐like polymers based on 11‐aminoundecanoic acid, that can be obtained in high purity and at a multigram scale are described. Free radical polymerization allows modification of the polymer with a wide variety of comonomers. The materials presented significantly enhance adhesion, are thermally stable at temperatures up to 350 °C, and are compatible with state‐of‐the‐art high‐energy LiNi0.6Mn0.2Co0.2O2 (NMC 622) cathode materials. It is also shown new recycling pathways made possible by the reversible pH‐dependent water‐solubility of the materials.
