The paper discusses the main patterns of structure formation and the production of highly filled polymer composite materials based on a deformable particulate filler from rice straw (agricultural waste) and a dispersion of polyvinyl acetate (PVA) in water. t has been established that when using a deformable filler of rice straw powder, it is possible to obtain under high pressure (up to ~230 MPa) pressing DFPCM with the highly-filled type of structure and the content of dispersed filler up to ~90% by volume. Such PCM has a sufficiently high level of physical and mechanical characteristics - compressive strength ~104 MPa and elastic modulus ~ 3.0 GPa, which opens up opportunities for its wide application and production of products for various purposes from "green chemistry" materials.

The radical copolymerization of N-[3-(dialkylamino)-propyl]methacrylamides with a number of (meth)acrylic amides and esters in organic solvents over a wide range of molar ratios has been studied. Co-polymerisation constants for five polymerisation systems in 1,4-dioxane and toluene have been determined by the Feinman and Ross method. The influence of the solvent on the kinetics of the copolymerization of the studied monomers was found, which manifests itself in a change of the reactivity ratios of the monomers upon varying the polarity of the medium. For the obtained polymers, the presence of thermosensitive properties in aqueous solutions and the effect of the concentration and composition of copolymers on their solubility in water were shown.

In this paper, the process of technological design of small-sized carbon fiber parts with complex geometry used in the design of unmanned aerial vehicles is considered. Approaches to the placement of splicing points in preform layers are presented. Regularities have been established that relate the number and location of splicing points in the reinforcing layers of carbon fiber reinforced composite and its mechanical characteristics.

The transfer of mixtures of hexane and toluene in thermoplastic polyurethanes used in the production of tanks for temporary storage and transportation of liquid fuels has been investigated. The standard methodology for estimating the diffusion permeability of polymers is not the basis for modeling the natural loss of fuels during storage. A model for estimating natural loss is proposed, the equations of which describe the linear dependences of the decrease in the mass of fuels in tanks in the coordinate of a conditional time equal to the square root of time. The efficiency of the proposed model depends on the composition of the hexane-toluene mixture, since the composition of the mixture affects the limiting stage of the process, which determines the dependence of the natural loss either on the diffusion rate of the fuel in the tank shell, or on the volatilization of the released fuel from the outer surface of the tank.

The question of the efficiency of turning processing of thermoplastic polymer materials with cutting ceramics is considered. The fact of a decrease in the values of the cutting force when turning the investigated thermoplastics with a tool made of ceramic material KNT16 was experimentally established. It has been experimentally proven that turning caprolon and fluoroplastic using a KNT16 cermet cutting insert leads to the formation of a supramolecular structure of a high degree of homogeneity.

The fact of increasing the elasticity of polyethylene gas pipelines in the process of long-term aging has been found. resumably, the increase in elasticity is due to the accumulation of mercaptans present in natural gas in the wall of the polyethylene pipe. It is shown that a specific mechanism for increasing elasticity during long-term operation consists in creating conditions for the development of secondary necking.

It is shown that the adhesive bonding of microfluidic chips made of polymethylmethacrylate, bonded with domestic glues SM Chemie 301 and SM Chemie 700, withstand pressure up to 0.3 MPa (1 hour), as well as dynamic loads arising from repeated temperature changes from 60 to 95°C. These adhesives do not inhibit the polymerase chain reaction and can be recommended for bonding microfluidic chips for this method of molecular diagnostics.
