Effect of nano-sized modifications of titanium dioxide (titania) with anatase and η-TiO₂ structures on structural parameters and properties of nanocomposites based on 1,2-polybutadiene – Kuzmicheva G.M., Yulovskaya V.D., Domoroschina E.N., Obolenskaya L.N., Ivshina A.G., Karpova S.G., Kopylova E.V.,. Savinkina E.V. (P. 6)

Effect of nano-sized modifications of titania (NST) prepared by sulfate technique (anatase and η-TiO2 ) and commercial Degussa P25 on properties of their composites with 1,2-polybutadiene (1,2PB) is studied by a complex of methods. Compositions were prepared by laboratory rolls. Curative group (sulfur, zinc oxide, stearic acid, dibenzothiazolylsulfide and tetramethyltiuramdisulfide) was introduced fist and then masterbutch of NST. The NST structure is shown to affect the degree of interaction between 1,2PB and titania. Effect of titania structure on the interaction between 1,2PB and titania is shown. Titania introduction results in decrease of glass transition temperature, i.e. extends the temperature range of the material working capacity.

Key words: 1,2-polybutadiene, nano-sized titanium dioxide (titania), X-Ray diffraction under large and small angles, IR-spectrometry, EPR, electron microscopy, DTA, sorption capacity, specific surface

Study of the Surface Morphology of Elastomers Modified by Gaseous Fluorine and its Effect on the Friction Properties – Nazarov V.G., Stolyarov V.P., Pyatov I.S., Maksimova Yu.A., Vasileva S.N., Mikhaleva L.A. (P. 12)

Effect of surface fluorination on the surface layer morphology of a number of rubbers under dry slip friction on steel, duralumin and bronze have been studied. The higher effect is shown for compounds based on butadiene-nitrile and ethylene-propylene rubbers. Surface fluorination results in a decrease of sliding friction coefficient due to the reducing of adhesive contact in a rubber-metal pair. The reducing could be from 2.5 to 20 times depending on the type of rubber.

Key words: rubbers, surface modification, fluorination, surface morphology, coefficient of sliding friction.
