The results of a study of mixing compositions based on polypropylene and vegetable fillers modified with an enzyme preparation are presented. During the experiment, the optimal modification time and the ratio of the volume of water to the mass of the vegetable filler during modification were determined. Physical and mechanical tests revealed that the composites with the modification were superior to the basic composites without the modification.

The effect of protective methane diffusion flux on the properties of polyethylene pipeline walls is proposed to be taken into account. It has been suggested that the protective diffusion flux initiated by the high-pressure system in the gas pipeline suppresses the oxygen diffusion process of air that occurs under atmospheric pressure.

The modification of low-density polyethylene/polybutyleneterephthalate (LDPE/PBT) polymer composites with organoclay was carried out and the main physical and mechanical properties of the obtained materials were studied. It has been found that organoclay has a significant effect on the basic properties of polymer composites. It is shown that such indicators as fire resistance, melt viscosity, density, heat resistance and deformation-strength properties of composites containing organoclay differ noticeably from similar parameters of the parent material. In this case, the change in properties is due to the influence of organoclay particles on the supramolecular structure of composites LDPE/PBT.

The deformation-strength characteristics of films made from a mixture of HDPE and LLDPE modified with chalk were studied. It is shown that the introduction of a chalk concentrate of more than 16 wt.% (the content of chalk concentrate is 20 wt.%) has a negative effect on the strength and relative elongation at break of the composition of HDPE with LLDPE, as well as on the strength of the welded joint of polymer films. The strength of the films in the longitudinal and transverse directions significantly depends on the composition of the composition. The strength of the weld, obtained by ultrasonic welding, decreases sharply when the chalk content in the system is more than 16 wt.%. The introduction of more than 10 wt.% LLDPE into a HDPE-based chalk-filled composition is inadvisable..

The radical copolymerization of butyl methacrylate with p-cyclopropyl styrene (I) and its monochlorine- (II), gemdichlorine-substituted derivatives (III) has been carried out and the basic regularities of formation of functionally substituted cyclopropyl styrene have been revealed. The composition and structure of the synthesized copolymers have been established. The copolymerization constants have been determined, the Alfrey–Price Q–e parameters and the microstructure of copolymers have been calculated. It has been established that the new copolymers are characterized by good optical indices (nD20 =1.640−1.650). For BMA + (I–III) copolymers in the range of 400−1100 nm, the base light transmission is 88−90%. It has been shown that the copolymers obtained from these monomers show excellent plasticity, due to which they can be used in making of small-sized injection molding products with improved exploitation properties. The characteristic viscosity of BMA + (I−III) copolymers is [η] = 0.90−1.02 dl/g. The copolymers based on BMA + chlorinated cyclopropyl styrene show incombustibility, whereas BMA-styrene copolymers are self-extinguishing. It has been found that the obtained copolymers show greater thermal stability than polystyrene itself. The copolymers obtained on the basis of chloro-substituted cyclopropane show optical transparency, which is an important characteristic for their application in optics.

The structures of novolac monoalkyl(C8–C12)phenolformaldehyde oligomers modified with imidazolines based on fatty acids of sunflower or corn oils and polyamines – diethylenetriamine, triethylenetetraamine, polyethylenepolyamines were investigated by IR-spectroscopy. As a result of the analysis of the initial and final products, a reaction mechanism is proposed. Optical densities of the absorption bands of the main functional fragments were calculated, and the regularities of the changes depending on the qualitative and quantitative composition of the oligomers were studied.
