Synthesis of Allylcaprylate-Styrene Copolymers With Styrole and Their Research as a Viscosity Additive to Lubricant Oils

Abstract

The article presents results of copolymerization of allyl ether of caprylic acidallylcaprylate with styrene in line with radical mechanism, the influence of the main factors -the composition of primary monomers and initiator consumption on the process, as well as results of studies synthesized copolymer as a viscosity additive in the composition of lubricating oils. It found that samples of synthesized polymer compounds are on a par with industrial additives of the polyalkylmethacrylate type on improving viscosity-temperature properties, but have higher operational characteristics than industrial additives in terms of resistance to thermal effects due to the stabilizing effect of styrene units. The study into samples of synthesized copolymers as oil additives showed that depending on specific requirement, a polymer compound of any molecular weight can be synthesized in high yield for use as viscosity additive for these oils.
