The molecular weight distribution of monoalkyl (C₈-C₁₂)phenolformaldehyde oligomers, modified benzoguanamine and products of their interaction at high temperature with the esters of oleic acid and aliphatic alcohols by means of gel- chromatographic method has been investigated. The dependence of the weight average and number average molecular weights, polydispersity of initial components and the final products from the composition of the esters have been studied. The regularities and assumptions about the processes, occurring in the interaction of oligomers with esters have been brought to light.

Identify some the physic-chemical properties of the synthesized graft copolymers of collagen crude skin and fibroin natural silk with polyacrylic acid. The dependence of solubility, density, and thermal properties of the copolymer and the component ratio of the synthesis conditions.

The review of a condition of a problem of reception and research polymeric nanocomposite, intended for use as wearproof materials is resulted.

The influence of the molecular weight of the stabilizer, concentration of the initiator, temperature on the regularities of the process of polymer dispersion of styrene was shown. Stable suspensions of TiO₂ nanoparticles in isopropyl alcohol stabilized with polyvinylpyrrolidone were obtained, and dispersion polymerization of styrene was carried out in their presence.

Upon interaction of formaldehyde with mixtures of phenol, phenolphthalein and 2-( β- hydroxyethyl)-3,3-bis(4'-hydroxyphenyl)phthalimidine in acide media new coolygophenolformaldehyde novolacs and crosslinked copolymers have been prepared. Their properties have been studied.

By a combination of IR spectroscopy and computer modeling methods the content of various forms of monomeric associates in solutions of higher N-alkylacrylamides and higher alkyl acrylates in toluene has been evaluated. It is shown that the main form of monomeric associates in the systems studied are poly-associates of N-alkylacrylamides, formed due to hydrogen bonds involving amide groups. The cooperative interactions of the higher alkyl linear comonomer groups caused by the dispersion forces did not show their influence.

The topography of the strength of welded joints was studied. Differences in the pattern of distribution of strength over the cross section of the weld for welds, welded in various process conditions fault detection and artificial joints, application of water and oil. A reduction in the properties 2 times.

The article presents the results of research work carried out by the specialists of the enterprises: "Nizhnekamskneftekhim", "POLYPLASTIC Group", Omsk carbon Group & "Kama plant of polymeric materials". Examined the new special grades technical carbon, their physical and chemical characteristics, the results of the tests of domestic concentrates of technical carbon and polyethylene pipe manufactured using serial and experimental concentrates of technical carbon in comparison with the import-analoques. The dynamics of moisture absorption of the polyethylene, filled with different types of concentrata carbon black were investigated. It is shown that the new carbon black grades P-type of production of the Omsk carbon Group of the similar complex of properties of the imported carbon. High-density polyethylene containing in its composition a brand OMCARB P72, is characterized by improved distribution of carbon, a reduced capacity for moisture absorption and high physical-mechanical properties.

The resulting compound of molybdenum - octamolybdate ammonium and molybdate zinc, which were introduced in PVC-plastics. It is shown that molybdenum compounds increase the fire-resistance of the source compound and significantly reduce the amount of smoke produced when it burns. Found that the introduction of molybdenum compounds in PVC-plastic leads to the improvement of basic physical and mechanical properties of the original plastic.

In the yielded work influence of silane coupling agent on physical-mechanical properties of the polymerous composites on the basis of polyethylene of low density and kaolin is considered. Law of change of properties dressing the polymerous composites depending on phylum and the quantitative maintenance of various ingredients is shown.

It has been shown that coatings based on polydimethylsiloxane and tris (methyldiethoxysiloxy) iron have the ability to thermoinitiate self-healing. The effect of MQ-resins on the healing properties of this coating

A comparative study of the performance properties of basic polymers and polymer composite materials for pipes and special-purpose products was carried out. It was found that the composition based on polyphenylenesulfide is characterized by high strength, physico-chemical and gas barrier properties, as well as fire resistance compared to other polymeric materials.

It is shown that the joint action of higher polyalkyl acrylates and waste ПАВ products of the synthanols shop gives a noticeable synergistic effect of improving low-temperature properties of the highly paraffinic and highly resinous oil of the Yuzhno-Tabaganskoye deposit. Polyalkyl acrylates are effective depressants and asphaltene-resin-paraffin deposits (ARPD) inhibitors while syntanols produce a low effect. However, their co-introduction leads to a decrease in the pour point by 6-9 ° C and an increase in the degree of inhibition of ARPD by 7-8%.

The kinetics of high temperature aging of glass-filled PA6 composites painted blue phthalocyanine pigment (sFTP). The calculations used to predict properties of the painted material under specified conditions. It is established that effective stabilization system allows to save the color and properties of glass-filled PA6 virtually unchanged a long time when exposed to high temperatures.

The influence of the chemical nature of the polymer used for the production of tanks, the quality of the fuel during its storage. The change in fuel quality during storage in reservoirs on the basis of polyurethane and a multilayer polymer film is determined by the content of low molecular weight polymer fractions. When using rubber additionally, the fuel quality is determined by the content of the plasticizer. Extracted from rubber carbon black affects the result of determining the quality of the fuel after contact with the polymer material.

The paper considers the technological processes for the production of nonwovens by bonding fibrous webs with the creation of sufficiently strong bonds between the fibers by means of ultrasonic welding. Optimum parameters of welding modes for fibrous webs, ensuring the greatest strength of the welded seam, are experimentally established.
