Study of the Properties of Latex Systems of Ultra Disperse Fillers – Tutorskii I.A., Dulina O.A., Es’kova E.V., Bukanova E.F. (P. 2 ).

Effect of different factors on particle dimensions of ultra disperse calcium sulfate and carbonate of bivalent metals obtained in situ in styrene–butadiene latex have been studied and best processing is established. Mechanical properties of unfilled rubber obtained from filled latex are of higher level.

Relaxation Properties of Hydrogenated Butadiene Acrylonitrile Elastomers – Abramova N.L., Zobina M.V., Akopyan L.A. (P. 5).

Hydrogenated butadiene acrylonitrile elastomers of Therban type have been studied by means of relaxation spectroscopy method. Activation energy of seven different relaxation processes was calculated. Data obtained were compared with values of activation energy obtained from temperature dependencies of strength and viscosity. The suggestion has been made on possibility of low crystallization ability of some Therban types (А–3406, А–4307 and 8884).

Water Transportation in Poly(3–Hydrobutyrat)/Natural Rubber Blends – Markin V.S., Pankova Yu.N., Shershnev V.A., Iordanskii A.L., Potapov E.E. (P. 9).

Kinetics of sorption–desorption and equilibrium sorption as well as diffusion of water in blends of natural rubber with poly(3–hydrobutyrat) of bacterial origin (contents 0–40 mass %) have been studied. Effect of blends structure is under discussion. The possibility to use the blends to medical purposes is suggested.

Structural Transformations at Obtaining and Processing of Black Batches Modified by Sewage Components – Korcha¬gin V.I., Shutilin Yu.F., Andreev R.А. (P. 11 ).

Processing and mechanical properties of SBR filled in liquid phase with water dispersion of carbon black, obtained at the stage of sewage clearing have been studied. Presence of fatty acids and other components in rubber stocks promotes plasticization and best distribution of ingredients in rubber. Improvement of properties is shown.

Effect of Polyethylene on Properties of Row Rubber Blends Based on Butyl Rubber – Markov V.V., Monakhova T.V.,Popov A.A., Reznichenko S.A., Alifanov E.V., Vlasenko F.S., Anosov V.V., Kornev A.E., Kukushkin Yu. V. (P. 15).

Cohesion strength, water– and oxidation resistance of row rubber blends based on butyl rubber and polyethylene of high (I) and low (II) pressure have been studied. Addition of II (in contrast with I) results in increase of cohesion strength, improves oxidation resistance and nearly doesn’t effect water resistance. The addition of II to butyl rubber is recommended to application as roof covers.

Effect of Sevilen on Properties of Row Rubber Blends Based on Butyl Rubber Reclaim – Markov V.V., Monakhova T.V., Popov A.A., Reznichenko S.A., Evreinov Yu.V., Alifanov E.V., Vlasenko F.S., Anosov V.V., Kornev A.E., Kukushkin Yu. V. (P. 17).

Cohesion strength, water– and oxidation resistance as well as resistance to static penetration of row rubber blends based on sevilen and butyl rubber reclaim have been studied. Addition of sevilen results in increase of cohesion strength and doesn’t effect oxidation resistance. Possibility to produce the row rubber blends of high static penetration is shown.

Production and Application of High–Dispersing Powders of Shungit and «Termin» as Mineral Fillers for Rubber Industry – Sheverdyaev O.N., Bobrov A.P., Kornev A.E., Sheverdyaeva N.V., Chernik G.G. (P. 18).

Production of high¬dispersed powders of shungit and termin (mineral fillers on the base of modified ash¬wastes after burning of hard fuel on the heat – electrical stations) in the planetary homogenizers have been described. Improvement of properties of rubber based on SBR and filled with these powders was shown.

Properties of Binary Alloy –Caprolactam/Stearic Acid – Puchkov A.F., Talbi E.V. (P. 21).

Phase diagram, solubility and IR–spectra of binary alloy –caprolactam/stearic acid as well as mechanical properties and swelling of rubber compounds with this alloy as disperser have been studied. Unlimited solubility of components in melt and limited in solid state is shown and molecular structure of alloy is presented.

Specific Features of Formation of Structure of Rubber Filled with Both Silica and Carbon Black – Khodakova S.Ya., Nikitin Yu.N., Filippova G.A., Kornev A.E. (P. 24).

Reological, mechanical and electrical properties of rubber compounds based on SBR filled with both silica and carbon black have been studied. Porous carbon black is recommended as disperser of silica. Participation of silica in donor¬acceptor interactions on a carbon surface is under consideration.

Textile/Rubber Material Resistant to the Effect of Aggressive Chemical Substances for Individual Defense Means – Zaripov I.N., Kashapov N.F., Kozyreva E.B., Fatkhutdinov R.Kh. (P. 27).

Twoside textile/rubber material of elastomer play based on butyl rubber/EPDM (40:60) have been developed. Elastomer composition is of high adhesion to polyamide. Resistance of composition to aggressive media is under comsideration.
