Abstract
Possibility of using elastic filler which received of the waste of tyres by conditions of high temperatures and deformation is investigated in rubber technology. The presented part of work has been directed on studying of morphological properties elastic filler, abilities to participation in vulcanization process elastomer material, comparison given kind of filler with the products of recycling of the worn out tyres presented in the modern market.

Abstract
Morphology of ternary polymer blend PVB/ PP//PS for porous materials preparation was studied. Dosages providing maximum dispersity level and continuity of PVB phase in PP matrix were determined. PVB forming co-continuous phase in PP was selectively leached resulted in porous material which can be used in a variety of applications.

THEORETICAL BASES OF CHEMICAL TECHNOLOGY

Abstract
The fundamental equation of adsorption and the adsorption isotherm for the process of immersion wetting are derived on the basis of Gibbs model. It is shown that in the case of low volatile surface-active component

Abstract
The thermodynamic method of description of the wetting process is suggested. Calculated formulae for the definition of F (free energy variation), S (entropy variation), U (internal energy variation) were obtained using the wetting process of a vertical plate. A suitable standard state is selected, the opportunity is shown for using calculated values for the prediction of the mutual substitution of two nonmiscible liquids on the solid surface. The possibility of application of the well-known thermodynamic relationships at such description of the wetting process was discussed

Abstract
There has been received mathematical description of continuous equilibrium evaporation process with chemical reaction. The criterion of multiple steady states occurrence is determined. Their stability is estimated and bifurcation diagrams are also constructed.

Abstract
Are investigated equilibrium differential evaporation process and process of complete condensation. Is shown, that each of these processes can be theoretically submitted as reversible. A processes combination in a sequence equilibrium vaporization - the total condensation even in case of components reversibility of derivates entropy occurrence at the expense of an temperatures inequality appropriate to differential equilibrium vaporization, and total condensation outlet temperature.

Abstract
By interaction of water solutions of K3[IrCl6] and Thiocarbamide (Thio, SC(NH2)2) at heating the complex of the composition [Ir(Thio)3Cl3] was synthesized. By the method of X-ray diffraction that the compound crystallizes in the monoclinic crystal system with space group C2/c, a = 13.492(3) Å, b = 8.264(2) Å, c = 24.979(5) Å, β = 92.79(3), V = 2782.00(1) Å3 , Z = 8. The compound has a structure with two crystallographically independent iridium atoms: the coordination sphere of the Ir(1) atom involves two Cl atoms and four S atom, whereas the coordination sphere of the Ir(2) atom consists four Cl atoms and two S atom. Coordination of molecules Thio to the Iridium is realized though the sulfur atom.

Abstract
Have been carry out research of interaction kinetic of bismuth-boron glasses consisting of: 70% Bi2O3, 30% Bi2O3; 70% Bi2O3, 27% Bi2O3, 3% MoO3; 70% Bi2O3, 26.94% Bi2O3, 3.06% GeO2 with 87% orthophosphoric acid. On initial interaction stage (under 3 min) establish a quota be chemistry reaction. At increase time (higher 10 min) of interaction primary role in heterogeneous process play stage of diffusion through lay at a surface.

Abstract
Has been displayed possibility of luminescent determination of Re, Mo and W on effect of extinction of luminescence Tb3+ and Sm3+. Presence of several lines of a luminescence at rareearth elements has allowed to carry out quantitative definition of transition and trace elements at their combined presence in complex oxide. The elative error of a method at most 0,08.
