ABSTRACT

In this article there are given the results of the investigations conducted at the Institute of Chemistry of Additives of the National Academy of Sciences of Azerbaijan Republic in the direction of preparation of polymeric compounds, which have different functions in the composition of lubricating oils depending on the meaning of their molecular mass and chemical composition. The results of the conducted investigations have shown that for the purposes of the improvement of thermal stability of viscous additives, initial monomers used for their analysis are underwent

to copolymerization with vinyl aromatic and carboxylic compounds. With the purpose of the development of polyfunctional polymeric compounds is conducted functionalization of oligomers of the high α-olefins. This way gives the possibility to develop lubricating compositions of the more simple structure, which leads to economic effect. On the base of oligomers of high α-olefins sulfonate, succinimide and thiophosphate additives were synthesized. Introduction of synthesized additives into the structure of lubricating compositions will give the possibility to develop lubricating compositions of various purposes.
