ABSTRACT
The disadvantages of the process of dehydrogenation of ethylbenzene in a two stage reactor are considered. It was shown that the dehydrogenation method in one step on a modern catalyst and a pressure below atmospheric has the following advantage: more efficient use of catalyst, increased selectivity, the practical absence of phenylacetyle and the impossibility of formation of diethyl- and divinylbenzenes. In existing installations the proposed method allows to achiewe more than 25% increase in styrene power.
KEYWORDS: styrene, ethylbenzene dehydrogenation, reactor.

ABSTRACT
The work shows the synthesis of metal-polymer complexes. Polyacrylonitrile, poly (styreneacrylonitrile), acrylic-butadiene-styrene polymer were used as the polymer base. Polymers swelling were carried out with metal salts of ZnCl2, CoCl2, NiSO4. The synthesized compounds were studied by IRspectroscopy and elemental analysis. The spatial structure of the complexes and the interaction mechanism were calculated by quantum chemical programming. The scope of such complexes is associated with their high antibacterial properties.
KEYWORDS: styrene, ABS plastic, polyacrylonitrile, acrylonitrile, zinc chloride, cobalt chloride, nickel sulfate.

ABSTRACT
The work of serial impregnated aramid cord yarns Arom-175, Rusar-200 and synthetic ropes of brands KS-4,5, KS-4,5 PL with their long-term operation in the frame of rubber products is simulated. The essence of the simulation is as follows: on specially designed devices simulating the operation of these materials in the power frame of the nozzles, the change in the state of the supramolecular structure and physical and mechanical parameters of the cord filaments and synthetic ropes in the process of cyclic and static tests is determined. It is shown that the cyclic strength of the Arom-175, Rusar-200 and synthetic ropes impregnated with serial solutions of cord filaments significantly exceeds the normative value for the nozzles. Marked advantage in the operation of synthetic rope, the KS-4.5 PL square braided core compared to a core in the form of a harness, the KS-4.5. Modeling of aramid materials in the product has shown that  their operation will reduce the breaking load and flexibility of the polymer chain in products with synthetic ropes and cord fabrics impregnated with a solution of R-138-12. Properties of cord yarns, impregnated with a solution of R-147с12 in the process of operation does not deteriorate. The practical value of the study — forecasting the performance properties of rubber products with aramid frame.
KEYWORDS: aramid cord yarns, synthetic ropes, impregnating composition, physical and mechanical properties, supramolecular structure, cyclic strength.

ABSTRACT
The work is devoted to the creation of swelling rubbers for the elements of packer equipment and colmatants used in oil and gas production. There was investigated the influence of the rubber nature in the swelling ratio of the elastomers modified with sodium–carboxymethyl cellulose. As ethylene-propylene rubber demonstrated a test result of the samples in water and «Polyeconol-Flora» drilling fluid at a temperature of 6°С it was stated that the biggest increase in volume at the best preservation of physical and mechanical parameters based elastomers.
KEYWORDS: swelling elastomers, colmatant, water-swelling agent, swelling ratio, drilling fluid.
