The article presents the results of a study of the addition of high-viscosity unimodal HDPE on the complex of physicochemical, rheological and strength properties of PE100. The analysis of thermal properties according to TGA/DTA data as well as the results of studying the composition of volatile products, and the molecular weight characteristics of individual components and blends are presented. The conducted studies have shown that the introduction of high-viscosity unimodal HDPE into bimodal PE100 makes it possible to control the rheological characteristics of the material, shifting the “melt breakdown” to the area of high shear rates, i.e. to increase the processability of the original PE 100, and expand the processing range, which may be useful in the production of extruded sheets and profile products. At the same time, the strength characteristics of the finished product will remain at the level of PE100.

A study on the effect of the structure of disperse-filled polymer composite materials (DFPCM) based on EVA grade 11306-075 and rice straw powder (RSP) with a particle diameter of 250 μm on the complex of rheological properties has been carried out.For the first time, a quantitative relationship of generalized parameters, type of structure and lattices with the rheological properties of dispersed systems based on EVA + RSP has been determined. It has been established that during the processing of DFPCM with the DS, LFS, and MFS-1 structure types by traditional methods (extrusion, injection molding, etc.), there are practically no technological difficulties. Systems with the type of structure MFS-2 and HFS have an increased viscosity (~7–15 times) in comparison with unfilled EVA; therefore, they cannot be processed.The results of the experiments and the approach developed in this work makes it possible to design DFPCM compositions with adjustable structural parameters and a set of properties, as well as to choose methods and technological parameters for processing them into products with a given shape, configuration, and dimensions.

The esterification reaction of polyvinyl alcohol with para-aminophenylcyclopropane carboxylic acyl chloride has been studied in order to obtain a diversified polymer containing fragments of polyvinyl alcohol and groups, amino and cyclopropane rings, as well as other fragments in the side links of the macromolecule. As a result of the study, a new polymer was synthesized and its composition and structure were determined on the basis of IR and NMR spectroscopy data. The properties of the synthesized polymer have been studied and it has been established that the modified polymer has high antimicrobial properties, which makes it possible to use it as an antimicrobial substance in medicine.

Russian glass-filled materials based on polyphenylene sulfide were used for the first time as a structural material of parts of miniature power supply devices based on stand-by chemical current sources. The advantages of these materials over traditional press materials are shown, the main of which are increased structural strength, reduced defectiveness of parts, reduced number of rejects, improved technical and economic production indicators. The application of polyphenylene sulfide-based materials allowed developing of power sources possessing unprecedented short activation time and building the high-tech industrial production of power supply devices.

The influence of quartz (silicon dioxide) content on main physical and mechanical properties of composites based on low density polyethylene is considered. It is shown that the introduction of a compatibilizer – a copolymer of high-density polyethylene with maleic anhydride – into the composition improves the properties and compatibility of the mixed components. The use of synthesized polyethylene wax as a plasticizer made it possible to significantly improve the deformability of highly filled composites. The method of thermomechanical studies shows the patterns of change in thermomechanical curves in the temperature range of 20 –200°C, depending on the concentration of quartz in the presence of a plasticizer and a compatibilizer.

The effect of antifriction additives on the process of ε-caprolactam anionic polymerization and on the properties of the synthesized samples has been studied. Motor oil, vacuum oil, household lubricating oil and polymethyl-siloxane fluid were used as antifriction additives. It has been shown that the introduction of antifriction additives at the stage of synthesis of oil-filled polycaproamide reduces the rate of anionic polymerization of ε-caprolactam. The influence of oils on the complex of physico-mechanical, thermal and operational properties has also been studied. It was found that the use of oils at the synthesis stage helps to reduce the coefficient of friction of the samples compared with the control sample. The best effect is observed when using 5 7 wt.% of petroleum oils (a decrease of 50 66% compared to the control sample). The water absorption of oil-filled polycaproamide samples containing petroleum oils is also reduced (by 37% compared to the control sample). At the same time, there is a deterioration in the physical and mechanical properties and an increase in oil and petrol absorption.

For the first time, calculations of a reinforced polymer composite material (ArPCM) based on T-25 fabric (VMP) and developed modified epoxy matrices with an active diluents (AR) of different nature, structure and characteristics (laproxides and laprolate), a complex of physical and mechanical characteristics were performed using a generalized 3D models of the elementary structural cell of the anisotropic material ArPKM and computational engineering systems (CAE). Calculations and experiments have shown that all the studied modified epoxy matrices can be used in the design of products from ArPKM, however, preference should be given to matrices with E-181 and DEG-1 grade Laproxides, which fully meet the strength requirements for designing products subjected to forces during operation.

The flow and heat transfer of a viscous chemically reacting liquid in a flat channel during the molding of composite products are studied. The main assumptions in the task definition were made on the basis of the high viscosity of the liquid and its low thermal diffusivity. The Brinkman equation is used as a motion equation. The flow is accompanied by a chemical reaction, resulting in a sharp increase in viscosity. The viscosity is considered to depend on the temperature and the degree of conversion. This, in turn, led to the inclusion of the kinetic equation of a chemical reaction in the mathematical model. The energy equation is denoted using a single-temperature model and includes dissipative heat emissions. The problem is solved for temperature first-order boundary conditions. The calculations are given for the Nusselt number distribution and the velocity profile transformation. The task was solved numerically by the finite difference method using iterations.
