The aim of the work was to investigate for the first time the possibility of modification of disperse mineral fillers (chalk and magnesium hydroxide) deodorizing shoulder straps containing fatty acids obtained by refining sunflower oil for create filled polymer composites. In the study of composites based on PVC found an increase in their tensile strength, strength reaches almost 50 % increases. Accordingly, the relative elongation of these polymer composites increases. Shown to increase toughness with increasing content of modifier, with a greater increase in toughness for chalk than magnesium hydroxide for polyester resin composites. The maximum increase of toughness is more than 50 %. Thermomechanical studies have shown that the heat resistance of composites mainly increases with modified fillers.

The work deals with the results of using the cotton fiber as the purest and most natural cellulose, as well as a raw material for the production of various chemical products. The necessity of cotton fiber preparation for its use in the chemical industry and expediency of its drying via a filtration method has been substantiated. The geometrical parameters of individual cotton villi, physical and mechanical characteristics of the layer were experimentally investigated. Under the action of pressure drop the effect of the cotton fiber layer height on the porosity, equivalent diameter, through which the heat agent is filtered, the specific surface area and the pressure loss were analytically determined. The experimental results regarding the pressure loss in a layer of cotton fiber during filtration drying are presented from the standpoint of the internal problem of hydrodynamics. The results of heat agent filtration through a cotton layer at different weights and heights of the layer are presented as a functional dependence ΔP = f(υ0), and changes in the layer porosity as ε = f(υ0). The generalization of the experimental data is represented as a dimensionless complex Eu = f(Re), and the dependence of the hydraulic resistance coefficient as a function of the Reynolds number ξ = f(Re). The results obtained in a dimensionless form make it possible to predict the energy costs for creating a pressure drop (under the same hydrodynamic conditions) when designing a new drying equipment.

Some underreported aspects of polypyrazolylborate chemistry are explored, in particular novel lanthanide coordination chemistry and zwitterionic ligand replacements of this so-called "scorpionate" class of ligands. The application of these ligands to future materials engineering is postulated and, finally, the historic relevance of the topic to L'viv is described.
