A hydrolyzed copolymer of styrene and maleic anhydride loaded with the brilliant green dye has been synthesized and described by the methods of IR and UV spectroscopy. A film based on such polymer showed a chemisorption properties with respect to ammonia, sulfur dioxide, hydrogen sulfide, but the film is inferior in these properties in comparison with films of polymethacrylic acid loaded with the same dye.

A method for the preparation of diethylene glycol diester of synthetic oil acids by nanocatalyst that provides ecological purity and economic profitability is considered. The plasticizing properties of the synthesized diester have been studied and it has been found that the plasticat of the test ester has a higher plasticizing property than industrial dioctyl phthalate and dioctyl adipate, which is of interest as an effective plasticizer for polyvinyl chloride.

For example, the experimental data obtained in the study of the curing process of thermosetting semi-finished materials (prepregs) polymer composite materials (PCM) showing the methodical possibilities of modern instruments for thermal analysis differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and Thermo-mechanical analysis (TMA) that allow you to examine and forecast the change of technological properties of prepregs in wide temperature range.

Factors determining the dimensional accuracy of products made of PTFE and composite materials based on it are investigated. Technological methods aimed at increasing the accuracy of manufacturing blanks and reducing waste in the manufacture of seals made of fluoroplastic composites are proposed.

The influence of the content of filler and the modes of laser action on the process of sintering of ceramic-polymer compositions based on modified polyvinylidene fluoride-2M was investigated. Ceramics of the lead zirconatetitanate system (ZTS-19M) were used as the filler. A comparative analysis of the quality of sintering has been performed on a number of parameters, depending on the composition and parameters of the laser treatment.

We have investigated the influence of some organic substances on solid state polymerization of acrilamide under combine action of high pressure (0.5-2.0 GPa) and shearing deformation. Some substances don’t act on polymerization process, another one slow down the process; we can not fined no any substance, which accelerates polymerization. The influence of organic substances with spherical molecules was very weak. Aromatic substances demonstrate strong effect of speed reducing. Speed reducing effect increased with increasing of number OH-group in organic molecule. Molecules of aromatic substances destroy intensively crystal structure of monomer despite of spherical molecules.

The mechanical properties and structure of composites filled with short basalt fibers (SBF) based on blend of polypropylene (PP) and metallocene ethylene-propylene elastomer (mEPE) are studied. It has been shown that the introduction of SBF in the PP/mEPE blend while ensuring good adhesion fiber-matrix by adding maleated polypropylene (MAPP) lead to significant increases in the modulus of elasticity and the tensile yield stress. When tested with notched specimens, the impact strength of PP/mEPE/SBF/MAPP composites improves with increasing fiber content. This trend is also observed in the case of un-notched specimens only at low test temperatures. To explain the observed phenomena, the influence of introduced fibers and test conditions on crack nucleation and crack propagation is proposed.

In articleare presentedresults of the modified polyethylene of low pressure with siliceous fire-retardant on the basis of silicates and silane. Influence fire- retardant on combustibility and possibilities of increase of fire resistance of the modified polyethylene with fire- retardant without deterioration is investigated.

The possibility of using syndiotactic 1,2-polybutadiene as a polymer base for the production of electrically conductive polymeric materials for 3D printing is shown. The influence of the nature and content of the plasticizer on the electrically conductive properties of polymer materials is determined.

The paper presents information about some of the ways of molecular weight polybutyl methacrylate regulating, which synthesized by radical polymerization method . Laboratory technique of polybutyl methacrylate synthesis with a predetermined molecular weight was developed. Polybutyl methacrylate has found application in restoration practice.

Spectrophotometry and microscopy was studied comparative resistance to light and heat aging of monofilm, polyamide (PA) and multi-layer high barrier thermosetting film (MTSF), the structure of which, along with layers of PA also includes layers of high density polyethylene, copolymer of ethylene and vinyl alcohol, and adhesive. For this, film samples were exposed to unfiltered light of a mercury lamp at 50°C.It is established that a lower aging resistance has MTSF, in the case where there has been considerable decrease in transmittance in the ultraviolet and in the visible region of the spectrum. After 50-hour irradiation MTSF experiencing shrinkage is mainly due to the outer and inner layer of PA.
