Effect of Alkyl Halide on Stability of Butyl Rubber Suspension in Methyl Chloride – Sofronova O.V., Markina E.A., Chelnokova S.M., Sakhabutdi­nov A.G. (P. 5).

Co­polymerization of isobutylene with isoprene in methyl chloride in the presence of alkyl­chloride­modified aluminum­chloride­based catalyst system was studied. Increase of stability of butyl rubber dispersion in methyl chloride as well as better dispersion properties in presence of chlorinated isobutylene dimers and chlorinated propylene trimmers are shown by the method of molecular adsorption.

Synthesis of Electroconductive Carbon Blacks by Thermooxidizing Pyrolysis of Hydrocarbons. Phenomenological and Mathematical Models of Process – Razdyakonova G.I., Surovikin V.F. (P. 24).

Processing of еlectroconductive carbon black production is reviewed. The phenomenological model of porosity change of carbon black particles is described taking the approach that the porosity is formed during oxidation of the particles with gases of full burning of hydrocarbons in a reactor. The equations connecting product properties and processing parameters are suggested. The equations of mathematical model of total process are presented and adequacy of them to experimental results is shown.

Key words: еlectroconductive carbon black, model of change of porosity, phenomenological model of particles, mathematical model of process.

Grinding of Ethylene­Propylene­Diene Rubbers by the Method of High­Temperature Shear Deformation – Solomatin D.V., Kuznetsova O.P., Prut E.V. (P. 29).

Monodisperse rubber powders with the predominant fraction of particles of 0.315­0.63 mm in size was prepared by the method of high­temperature shear deformation from EPDM rubbers with different content of paraffin oils. Grinding of rubbers results in formation of particles of core of high­density cross­linking, surrounded by a layer of low­density cross­linking. This gel fraction is of cross­linking density comparable with that of initial rubber.

Key words: EPDM, grinding, rubber powder, paraffin oil, cross­link density, mechanical properties
