A review: Oils, greases, lubricants, additives with superior properties

Abstract

The history of biodegradable lubricants has been presented in a series of articles, works and patents. A lubricating oil with good friction properties contains a lubricating oil and at least one additive, which has friction reducing properties, which is a block copolymer containing hydrophobic segments and polar segments. A complex composition of polymers used for the production of greases is reported by Lubrizol company researchers. Additives for lubricating oils with the ability to improve the viscosity index and shear stability were proposed by Mitsui. The creation of lubricating fluids with increased energy efficiency and high durability is the subject of a patent by the company Exxon Mobil.
