ABSTRACT
The aim of the work was to identify the correlation between dynamic and stationary deformation modes of polybutadiene (PB) using the empirical Cox-Merz method. To calculate the characteristics of stationary loading, PB samples of different manufacturers were selected based on the compounds of neodymium (I), cobalt (II), nickel (III), and titanium (IV). All samples had similar Mooney viscosity ~ 45 units. In the course of the work, it was noted that the best agreement between the experimental data and the calculated values for polybutadiene rubber is observed when the shear rate is equal to the frequency and the value of tangential stress at shear t(γ ⋅ ) from the loss modulus t(γ ⋅ ) = G″(ω)/sinδ(ω). The value of the highest Newtonian viscosity for samples PB II and III is larger, in comparison with PB I and IV. For PB II and III, a decrease in the flow index n and viscosity coefficient K is shown in the range of shear rates from 0,333 s-1 to 20,0 s-1 (Ostwald-de-Waele equation). However, the region of turbulent flow regime for these samples occurs at higher shear rates.
KEYWORDS: butadiene rubber, shear rate, Ostwald-de-Waele equation, flow index, highest Newtonian viscosity, elastic turbulence.

ABSTRACT
The article deals with the issues of modification of petroleum bitumen with polymer-containing organic liquids after their use in the process of high-temperature washing of polymerization equipment at enterprises for the production of thermoplastics. The use of thermoplastics and elastoplastics as modifiers of bitumen, materials based on it, including protective coatings, asphalt concrete, is one of the ways to improve their physical and mechanical properties. It is especially important to increase the stability of asphalt concrete, bitumen-based protective coatings in conditions of temperature differences. On the basis of the obtained experimental data, compositions for bitumen modification were developed based on the used organic flushing fluids. Their influence on the change in the physical and mechanical properties of bitumen was studied, the optimal temperatures for washing polymerization equipment with experimental compositions of washing liquids were determined. The physicomechanical properties of bitumen modified with various compositions of polymer-containing flushing liquids and protective coatings based on it were investigated. As a result of the studies carried out, it was found that in order to reuse flushing fluids after cleaning the polymerization equipment, the optimal concentration of dissolveddegraded polymers is 10-12% of the mass. The highest efficiency of improving the physicochemical properties of bitumen was shown by samples of polymer flushing fluids based on degraded polypropylene, polyethylene, and polyamide-6. The data obtained in the course of the research allow us to consider the used flushing polymer-containing organic liquids as a secondary raw material source for obtaining modifiers of petroleum bitumen and building composite materials based on them. The most expedient is the use of the used polymer-containing flushing fluid in the production of asphalt concrete for the construction of highways, waterproofing of concrete and metal structures, pipelines, including above-ground and buried ones.
KEYWORDS: flushing fluid, bitumen, modifiers, thermoplastics, polyamide-6, polyolefins, thermochemical destruction, dispersion, ductility, adhesion.
