The authors conducted a broad study of the synthesis and application of the different polymer lubricant additives, among which the sulfur- and phosphorus-containing polymer multifunctional additives are especially important. The sulfur- and phosphorus-containing polymer multifunctional additives were created by treating the initial polymer compounds by phosphorus pentasulfide and neutralizing the obtained acid reaction products by different compounds. It is believed that the main products from the reaction of phosphorus pentasulfide with polymer compounds is a polymer with a phosphinodithioic acid group as a crosslink. The acid groups were then neutralized using various metal bases. The properties of the additive are given.
