“…The intrinsic viscosity (η) was found from the graphical dependence of ηred = t (C) by extrapolating the lines to the zero polymer concentration. 3 Studies of hydrodynamic properties of hydrolyzed mixtures of HPAA-PV in a wide range of concentrations (0.001-1), pH, temperature (Fig. -1), etc., show that polymer mixture solutions obey the general patterns characteristic of polymer solutions containing ionizing functional groups.…”

In this article are shown soft dosage forms (ointments) obtained based on polymer reagents. Water-soluble polymers are synthesized based on acryl-containing compounds. Aqueous solutions of polymeric reagents and their physical and chemical properties (viscosity and optical density) have been investigated. It was shown that polymers can be used for the transportation of drugs. The polymer macromolecule at pH = 3.5 is in a folded state. The macromolecule is unfolded with increasing pH. This leads to an increase in viscosity, the optical density does not change. The drugs are passed toxicological control. Based on toxicological investigate and analysis of the data obtained, it was concluded that the polymers have insignificant functional accumulation. Do not show skinresorptive and allergic effects. The compatibility of polymers with antibiotics (levomycetin, levomycetin sodium succinate) was investigated. To establish the compatibility of copolymers with the antibiotics levomycetin, levomycetin sodium succinate and neomycin sulfate, it is necessary to identify the antimicrobial activity of antibiotics, which is determined by diffusion into agar. The properties of soft dosage forms (ointments) were sinvestigated using the agar diffusion method, it was shown that antibiotics are compatible in combination with the polymer reagent and their antimicrobial activity was revealed.

“…Upon receipt of composite coatings such as graphite-copper, carborund-copper increases electrical conductivity, resistance to friction, does not oxidize when interacting with oxygen in the air, chemically attaches to all aggressive aqueous solutions compared to precious metals, and reduces the coefficient of friction. [7][8][9] The main objective of the study is to obtain a coating of modified nickel phosphide with high wear resistance and low friction coefficient by incorporating into the composition of nickel phosphide a Ferro phosphoric powder, which is an auxiliary product of production.…”

The article presents the results of research on the production of chemical films of nickel phosphide with the addition of some impurities such as ferrophosphorus and carborundum. Magnetic stirrer and purge method were used for research. As a result of the study, when analyzing the quality and composition of the obtained films, it was found that the quality of the films obtained by purging is high. With the help of scanning electron microscopy, the quality of the obtained film was analyzed, the elemental composition was determined.
