“…The properties of polymeric materials obtained on their basis are unique, providing a wide range of their practical applications in agriculture, medicine, petrochemistry, and chemical synthesis. In this regard, it should be noted that the synthesis of "smart" copolymers with a high moisture absorption capacity, based on available and inexpensive raw materialsunsaturated polyesters cured with ionic vinyl monomersand its further study is an important direction [3][4][5][6].…”

Introduction. With the development of the chemical industry, the search for and synthesis of new, and modification of the existing nanocatalytic systems are of great importance. In view of this, the preparation of new catalysts by immobilization of transition metal metals in a polymer matrix becomes an important direction in chemical synthesis. Purpose of this work is to submit experimental data on the synthesis and study of the catalytic properties of silver and nickel nanostructures, immobilized in polymer matrices, based on a binary system of unsaturated polyester – polyethylene glycol maleate – with acrylic acid. Nanocomposites have been obtained by reducing a solution of nickel and silver metal salts with sodium hypophosphite in the presence of an ammonia solution of silver chloride. Methodology. By the methods of spectroscopy, microscopy the sizes, structure and morphology of polymer-stabilized nanoparticles are determined. Results. The obtained nanocomposites contain isolated Ag0 nanoparticles with a diameter of 60±10 nm, predominantly spherical in shape and metallic Ni0 with a cubic shape of 70±10 nm, uniformly distributed in the polymer matrix, as well as agglomerates on the surface of the polymer matrix, the dimensions of which vary within 150–200 nm. The catalytic activity of the synthesized nanocomposites, which show high efficiency in comparison with the standard metal catalysts, has been also studied.

Understanding the physical and chemical properties of new-generation polymeric materials during the synthesis is very important in obtaining the desired product in design and production. Chemical, thermal, and physical parameters as well as degradation kinetics of the resins developed especially in recent years are the main stages that determine the polymer composition process that affects material selection. In this study, the potential to use RAFT agent (2-cyano-2-propyldodecyltrithiocarbonate, CPDT) in the synthesis of new polymers based on polypropylene fumarate phthalate has revealed important properties. To exemplify, the concentration of the RAFT agent affects the polymer-based mesh density associated with the yield of the product. Changes in swelling behavior and thermodynamic parameters of polymers synthesized in the presence of RAFT agent were observed. Chemical composition and stability characterizations of the synthesized grafted polymers were performed by FT-IR, 13C, 1H-NMR spectroscopy and TGA. The grafted polymers analyzed by SEM morphology were found to have hydrogel sorption potential showed signs of a loose surface and the formation of a layered and porous structure in comparison with the grafted polymers. The resulting compounds have a high swelling capacity and increased yield. At the same time, this study will shed light on the thermodynamic calculations of the graft polymers in order to determine or predicting the polymer composition. Graphical abstract
