Abstract
The dependence of the colloidal stability, effective viscosity, penetration, and yield stress of low-temperature polymeric greases on the composition and characteristics of the dispersion medium was investigated. Various types of low-viscosity oil with known fractional and group composition were used as base oils. The effect of the concentration of the two-component thickener of high- or low-molecular polypropylene and the proportions of its components on the main physicochemical characteristics of the polymer greases was determined. The dependence of the structure and properties of the polymer greases on the concentration of lithium stearate was established.
