Abstract

This article examines the effect of esters on the resistance to mechanical degradation of ester thickeners as viscosity modifiers in thickened isoparaffin oils. The main reason for triggering such engine oils is the destruction of the thickener. The introduction of the ester should increase the polymer's resistance to rupture when passing through mechanisms with small gaps – gear oil pumps, in the lubrication system of an internal combustion engine. Also, esters with long alkyl chains should increase the solubility of polar thickeners in low-polar base oils, which can expand the application ranges of such thickeners and increase the resistance of thickened oils to low temperature-to eliminate the precipitation of the thickener at low temperatures. Depending on the thickening capacity of the viscosity modifier, its application may allow the production of motor oils with an extended service life in the entire range of viscosities of commercial oils according to SAE J300.
