“…Polyvinylpyrrolidone (PVP) has attracted much attention due to its impressive properties, such as its biocompatibility, nontoxicity, solubility in water and many organic solvents, pH stability, affinity to complex both hydrophobic and hydrophilic substances, and status as chemically inert in physiological reactions [34]. The use of PVP opens additional opportunities for the synthesis [35] and stabilization of metal nanopowders [36,37], modification of various substances [38,39] and materials [40,41], improvement of modern technologies [42,43], production of new functional materials [44,45], and the respective expansion of their fields of use [10,46].…”

The synthesis and study of metal-containing hydrogels, particularly those filled with nickel nanoparticles, is currently of interest to many researchers. This paper presents the results of an investigation of the structure and properties of Ni(0)-filled composites on the basis of 2-hydroxyethylmethacrylate copolymers (HEMA) with polyvinylpyrrolidone (PVP) and their hydrogels. The authors of the article are the first who propose the method to produce these materials by combining the processes of polymer matrix synthesis and a reduction of Ni2+ ions. Synthesis is carried out in one stage without complicated equipment and is technologically simple. It is determined by thermometric research that the temperature conditions required for the chemical reduction of Ni2+ are achieved due to the heat released during the exothermic reaction of HEMA polymerization in the presence of PVP. With the help of Fourier transform infrared analysis, and thermogravimetric and differential-thermal analysis, the formation of a crosslinked graft copolymer based on HEMA and PVP was confirmed, and its structural parameters, including the efficiency of PVP grafting, PVP content in the copolymer, and the molecular weight of the interstitial fragment of the polymer network, were investigated. The results obtained with scanning electron microscopy revealed that the size of the Ni(0) particles is about 500 nm. X-ray structural analysis of the composites obtained confirmed the existence of metal nickel particles. The strength, elastic, sorption, electrical, and magnetic properties of the obtained composites in the solid (dry) and elastic (swollen) physical states, depending on the composition of the copolymer and the content of the metal filler, have been investigated.

“…Водночас можливо припустити також утворення просторової сітки внаслідок хімічної взаємодії ПА-6 із ПВП. Вибір індивідуальних плівок для комбінування визначається комплексом властивостей окремих складників, необхідних для використання у конкретних умовах і одержаних за доступними методами [28]. Поєднання властивостей плівок на основі суміші ПА-6/ПВП і плівок із кополімерів пГЕМА-пр-ПВП повинно забезпечити ефект зміцнення гідрогелю.…”

The paper presents the study results of the molecular weight effect of polyvinylpyrrolidone (PVP) on the properties of composite hydrogels/polycaproamide membranes, which were obtained by modifying hydrogel films based on copolymers of 2-hydroxyethylmethacrylate (HEMA) with PVP by applying ultra- thin layers on the basis of a polyamide (PA-6) with PVP mixture. It was found that the interaction magnitude between the layers of composite membranes, as well as their properties – water content, tensile strength, salt and water permeability coefficients, largely depend on the molecular weight of PVP as in the original polymer-monomer composition and in the modifying PA-6/PVP solution.

“…(PVP) initiates the polymerization of hydroxyalkylene methacrylates as an active complexing agent [3][4][5], forms new polymeric random cross-linked matrices [6][7][8][9] and contributes to the formation of homogeneous polymer mixtures based on amphipolar polymers [10,11]. At the same time PVP intercalates montmorillonite (MMT) [12][13][14], which is the basis for the formation of thermoplastic nanocomposites, in particular of those based on polyamide and polypropylene mixtures.…”

The interrelation of physico-mechanical and technological characteristics of newly created nanocomposites on the basis of polypropylene (PP)/polyamide (PA-6) mixture with PVP-modified montmorillonite has been investigated. The significant impact of modified polyamide on technological, physical and mechanical properties and heat resistance of polypropylene has been determined. It has been established that the melt flow index of the resulting composites increases by more than 2 times, compared with pure PP. The hardness, modulus of elasticity and heat resistance of composites were found to be considerably increased in comparison with pure PP due to polypropylene mixing with modified polyamide. At the same time, the percent elongation and the forced-elastic strain of composites are reduced by 2 times.
