Modification of Isoprene Rubber by Monoesters of Maleic Acid Vasilev V.A., Khvostik G.M., Smirnov V.P., Morosov Iu.V., Nasyrov I.Sh., Bazhenov Iu.P. (P. 2).

Modification of isoprene rubber by monoesters of maleic acid and properties of modified rubber have been studied. Comparison with NR shows the best strength properties of both unvulcanized and vulcanized rubber as well as tear resistance of vulcanized rubber. Molecular and rheometric characteristics are of the same level.

Key words: isoprene rubber, modification, monoesters of maleic acid, strength properties

Improvement of Structure and Properties of Fluorine-Containing Rubber SKF-26 Zuev A.V., Kochetkova G.V., Ostrovskaya T.P., Taganova V.A., Pitchkhidze S.Y., Yurovskiy V.S. (P. 6).

Structure and properties of fluorine-containing rubbers SKF-26 and two its experimental analogues SKF-26/8 and SKF-26/10 have been studied. Measurement of tg at different frequencies was in use to evaluate branching of rubbers, MMR studied by means of gel-permitted chromatography. Mechanical and processing properties of technical rubber for rubber/metal seals were also studied. Lower MM and viscosity, minimal branching and maximal Mw /Mn as well as best processing properties were shown for SKF-26/8.

Key words: fluorine-containing rubbers, MMR, branching, mechanical and processing properties, rubber for rubber/metal seals

Coagulation of Carbon Black Aerosol in a Turbulent Stream Dmitriev K.I., Shopin V.M. (P. 20).

Process of coagulation of an aerosol of carbon black in a turbulent stream was studied. On the basis of experimental data it is drawn a conclusion on an intensification of process of coagulation of an aerosol with the growth of Dibutyl Phthalate absorption number parameter characterizing structure of disperse carbon black. Process of amalgamation of aggregates of carbon black is studied at sedimentation of an aerosol on a gas-permeable obstacle.

Key words: disperse carbon black, aerosol, coagulation

Possibilities of the Method of Dynamic Indentation in Estimation of Schungite Filling Degree of Rubbers Mosgalev V.V., Rudnitskii V.A., Shashok Zh.S., Kasperovich A.V. (P. 23).

Method of dynamic indentation was in use to estimate structure and filling degree by schungite of vulcanised rubbers based on crystallisable isoprene rubber SKI-3 and noncrystallisable styrene-butadiene rubber SKMS-30ARKM-15. Comparison with strength data as well as rubber/filler interaction is under discussion.
