The structural organization and thermomechanical properties of nanocomposites prepared from interpolyelectrolyte–metal complex (IMC) involving anionic polyelectrolyte, pectin AgNO3, cationic poly(4-vinylpyridine), have been investigated using the methods wide- small-angle X-ray scattering analysis. It is established that chemical reduction Ag+ ions in IMC by sodium borohydride results formation nanocomposite based on "pectin–poly(4-vinylpyridine)" interpolyelectrolyte (IPEC) Ag0...
Applying wide-angle X-ray scattering method, thermomechanical analysis, and differential scanning calorimetry, the structural organization properties of nanocomposites formed by chemical reduction Сu2+ cations in interpolyelectrolyte–metal complex (pectin–Cu2+–polyethyleneimine) under influence a constant magnetic electric fields have been studied. It has found that Cu2+ bulk leads to formation nanocomposite consisting interpolyelectrolyte complex, including pectin–polyethyleneimine...
New (bio)degradable environmentally friendly film-forming ionomeric polyurethanes (IPU) based on renewable biotechnological polysaccharide xanthan (Xa) have been obtained. The influence of the component composition colloidal-chemical and physic-mechanical properties IPU/Xa films, as well change their under environmental factors, studied. results IR-, PMS-, DMA-, X-ray scattering study indicate that incorporation Xa into polyurethane chain initiates formation a new polymer structure different...
Structure–property relationships in thermoplastic-apparent interpenetrating polymer networks (t-AIPNs), prepared by mechanical blending a common solvent of crystallizable polyurethane (CPU) and styrene/acrylic acid random copolymer (S/AA), were investigated means wide-angle small-angle X-ray scattering (WAXS SAXS), dynamic analysis (DMA), thermally stimulated depolarization currents (TSDC) techniques, dielectric relaxation spectroscopy (DRS), density, water uptake, deformation, strength...
Abstract Thermoplastic apparent interpenetrating polymer networks (thermoplastic‐AIPNs) were prepared at several compositions by melting and pressing of crystallizable polyurethane (CPU), based on butylene adipate glycol (BAG), styrene/acrylic acid random copolymer (S/AA). Structure‐property relationships in the thermoplastic‐AIPNs investigated means wide‐angle small‐angle X‐ray scattering (WAXS, SAXS), differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA),...
Abstract Pseudo-thermoplastic interpenetrating polymer networks (p-TIPNs) prepared by mechanical mixing of a crystallizable polyurethane (CPU) and styrene/acrylic acid random copolymer (S/AA) were characterized specific heat capacity measurements in the temperature interval 133–433 K, as well wide-angle small-angle X-ray scattering. It was established that: 1. Crystallizability BAG is main cause microphase-separated morphology CPU. 2. Limited miscibility CPU with S/AA significantly affects...
Abstract Novel polyurethanes (PUs) based on poly(oxytetramethylene glycol), 4,4′‐methylenediphenyl diisocyanate, and 1,1‐dimethylhydrazine (DMH) were prepared.

The level of environmental pollution is increasing year by year. Solving this problem requires the development and application new effective technologies materials for wastewater treatment processing accumulated waste. One alternative directions membrane technologies, in particular, biodegradable nanocomposite membranes. Anionic polyelectrolyte – Na-carboxymethyl cellulose with molecular weight Mw ~ 90000 cationic low chitosan were used to create these Polymeric membranes formed mixing...
The nanoporous structure of nickel vacuum condensates produced by the EB PVD method was investigated. nanoscale pores were analyzed using small-angle X-ray scattering (SAXS) and scanning electron microscopy (SEM) techniques. It observed that set these nanopores can be considered a bimodal system with characteristic sizes approximately 1–3 nm 20–30 nm. is assumed smaller form as result coalescence individual vacancies into clusters during vapour phase deposition in vacuum. These have close to...
