3314. SEGER F. M., AND SACHANEN, A. N. (Socony-Vacuum Oil Co., Inc.) Synthetic Lubricants. United States Patent 2,500,160, Mar. 14, 1950; appl. filed Feb. 7, 1948, Serial No. 6,993; 8 claims (Cl. 260-669). Chem. Abs. vol. 44, 1950, p. 4669.

Oil of at least 100 viscosity index and low pour point is prepared by heating noncatalytically straight chain normal, a mono-olefin (5-12 C atoms) and styrene to 500°-700° F. from about 10 hr. to about 1 hr., respectively. The molar proportion of the olefin in the charge is greater than the styrene. Wax from Fischer-Tropsch synthesis may be used as charge. 2 United States patents cited.
