This article investigates the thickening power of a hydrogenated polybutadiene-styrene with a molecular weight of 90,000 in three types of oil base stocks: KhF-12, SK-3, and a blend of 66% SK-3 with 34% NK-1. The results indicate that as the temperature is lowered, the relative viscosity of the compounded oils with a naphthenic-aromatic base stock (KhF-12) increases more rapidly than that of the oils formulated from a naphthenic-paraffinic base stock (blend of 66% SK-3 with 34% NK-1). The copolymer has a weaker thickening effect on naphthenic-paraffinic oil at temperatures from -10/sup 0/ to 80/sup 0/C. It is determined that with further increases in temperature, the differences in the thickening effect in oils of different compositions decrease continuously, and at 150/sup 0/C, these differences disappear.
