The additives of polymer type

Abstract

The paper presents the general data on various polymer additives – polyisobutylene, polyacrilates, polymetacrylates, oil-soluble polymers and copolymers of allyl and vynil monomers, the derivatives of alkylnaphtalines, alkylfenol, which improve viscous and depressor properties of the lubricants. While using polymer compounds undergo different processes of destruction and oxidation. To improve the stability, the aromatic fragments are involved in the polymers via various methods. The paper provides the results of the research surveys on the synthesis of the additives of polymer type with heat-stable, high viscous-temperature, depressor, anticorrosion, antioxidation properties, and their structure have been studied as well. It is noted that wide-range studies in the sphere of the synthesis and examination of the target, high-quality polymer additives are carried out in the Institute for the Chemistry of Additives of ANAS named after A.M. Guliyev. These additives as the depressor ones reduce the chilling temperature of the lubricants and improve their viscosity index.
