ABSTRACT
An analysis of the data has been carried out, which allows one to gain an idea of the possible mechanisms of the plasma decomposition of phenol in its aqueous solutions under the action of various types of discharge in various plasma-forming gases. It was found that the qualitative composition of particles capable of oxidizing phenol and the decomposition products is the same and does not depend on the initial plasma-forming gas and the type of discharge. The main reagents leading to the oxidative destruction of phenol are •OH radicals and oxygen atoms. Nitrogen oxides and ozone also appear in air plasma, and ozone in oxygen plasma. Data are presented on the kinetics of phenol decomposition (rate constants) in discharges of various types and different plasma-forming gases, as well as on the main products formed during decomposition. It was shown that the kinetics of phenol decomposition in all cases obeys the pseudo first kinetic equation on phenol concentration. The energy efficiency indicators of the action of various discharges are determined. In the case of a discharge of atmospheric pressure in contact with the solution, a direct relationship is observed between the change in the pH of the solution and its conductivity.

ABSTRACT
The paper presents the practical comparative properties of the antimicrobial activity of a number of synthesized polymers and copolymers based on styrene and acrylonitrile, as well as their metal copolymers obtained by mechanical mixing of antimicrobial additives and polymers, polymers and copolymers themselves, without additives, and are resistant to fungi and bacteria. Their active effect on both fungi and bacteria is shown. It has been established that the activity of the metal copolymers of styrene, acrylonitrile and butadiene exhibit great antimicrobial activity against both fungi and bacteria. This study is especially important and promising, since the solution to the issue of protection against microorganisms on the globe is currently especially relevant.

ABSTRACT
In the framework of the semi-empirical method PM3 and the unlimited Hartree-Fock method in basis 6-31 (d, p), quantumchemical calculations of cellulose and its derivatives with acrylic acid and acrylonitrile were performed. The thermodynamic parameters of the compounds are presented. Cellulose compounds with acrylonitrile and acrylic acid have a high calorific value, the values of which were determined by the methods of computational chemistry using quantum chemistry methods.
KEYWORDS: cellulose, acrylonitrile, acrylic acid, cellulose derivatives, calorific value.

ABSTRACT
Swelling of the elastomers based on butadiene-nitrile rubber modified by a combination of copolymer of acrylamide with potassium acrylate and sodium-carboxymethyl cellulose was studied in water and aqueous solutions of sodium chloride of different concentrations at a temperature of 80 °C. It was found that at this temperature the designed packer rubber is most effective during its contact with fresh water or aqueous solution of sodium chloride with concentration up to 6 %.
KEYWORDS: water-swellable elastomers, swelling ratio, aqueous solution of sodium chloride.
