In-situ Composites Based on Polyether Sulfone and Liquid Crystalline Polymer in Presence and Absence of Modified Nanofiller as a Compatibilizer – Das T., Adhikari B., Pandey K.N., Alam S. (P. 2).

Properties of Polyethersulfone/Liquid crystalline polymer blends in presence of nanosilica and epoxy have been studied by means of thermal, mechanical and structure methods. Introduction of Zn2+ ion coated nanosilica results in increase of compatibility of components.

Vulcanization of Halogenated Ethylene-Propylene Rubbers – Ronkin G.M. (P. 7).

Processes of vulcanization of halogenated ethylene-propylene rubbers have been studied. Dependence of mechanical properties of vulcanized rubbers on degree of halogenation is shown. Properties of chlorosulfo-ethylene-propylene rubbers are compared with properties of chlorosulfo-polyethylene and its advantages are shown.

Ozone-Resistant Vulcanized Rubber Based on Halogenated Ethylene-Propylene Rubbers – Ronkin G.M. (P. 11).

Properties of vulcanized rubber based on halogenated ethylene-propylene rubbers and their blends with unsaturated diene rubbers have been studied. High ozone-resistance of vulcanized rubbers based on individual rubber and blends is shown.

Modification of Carbon Black Surface by Hydroxyl-Contaning Oligomer – Kornev Yu.V., Lykin A.S., Shvachich M.V., Gamlitskii Yu.A., Bukanov A.M. (P. 13).

Method of modification of carbon black surface by hydroxil-contaning oligomer is proposed. Analysis of properties of rubber compounds and vulcanized rubber based on SBR with carbon black of modified surface leads to conclusion about increase of interaction between carbon black and elastomer matrix. Mechanism of formation of elastomers layers on carbon black surface is under discussion.

Polyurethanes Based on Acoustic Treated Polyethers – Mingaleev N.Z., Zinnurov Z.G., Kostina L.E., Galiullin A.F., Zenitova L.A., D yakonov G.S. (P. 16).

Effect of acoustic treatment time t at 60 and 80 °C of polyethers on their viscosity and mechanical properties of polyurethane has been studied. Maximum of polyethers viscosity is at t = 15 – 20 min. and correspondents to increase of polyurethane strength. Acoustic treatment of polyethers results also in decrease of polyurethane solidification time.

The Use of Hydrosilicates Co and Ni for Increase of Brass-to-Rubber Adhesion – Meledina L.A., Sakharova E.V., Kandyrin K.L., Gordon E.P. (P. 18).

The cobalt and nickel hydrosilicates were studied as the brass-to-rubber adhesion promoters. The initial level of cord to rubber adhesion is not much affected by these inorganic compounds, but the humidity aging test revealed their significant effectiveness. A great increase in the adhesive strength both before and after aging was achieved by combining the hydrosilicates with liquid organic polysulfide (Thiokol).

New technique of calculation of coefficient of thermal expansion of multicomponent elastomers compositions to determination of shrinkage after vulcanization has been proposed taking into account “linear” but volume concentration of ingredients. The accuracy of different equations is under consideration. Information about data base of coefficient of thermal expansion of different ingredients is presented.

About the Power Expended in Treatment of Rubber Compounds in Pressure Region of Screw Canal – Tatarnikov A.A., Burtelov L.V. (P. 35).

Equations for power expended in treatment of rubber compounds in pressure region of screw canal are presented. Geometric parameters of canal providing the minimum of this power are recommended.

Properties of Rubbers Based on Reclaim of Butyl Rubber Obtained by Radiation and Possibilities of Application of These Rubbers – Vagizova R.R., Khakimullin Yu.N., Stepanov P.A., Palyutin F.M. (P. 38).

Different methods of obtaining of reclaim of butyl rubber are under discussion. Mechanical and vulcanization properties as well as aging behavior of rubbers based on different reclaim types and of sulfur and resin vulcanization are compared. Advantages of radiation method are shown. The conclusion is drawn that elastomer materials of different purpose are obtainable.
