Abstract

A lubricating composition comprises a blend of a liquid aliphatic diester of a saturated aliphatic dicarboxylic acid, and a polyester, soluble in the diester and having the general formula ROOCR1COO(R2OOCR1COO)nR . . I where n is an integer; R is a C4-18 alkyl group (each separate R may be the same or different); R1 is a C4-14 alkylene group; and R2 has the formula <FORM:0861964/IV (a)/1> where x is 0 or an integer; y is an integer; x+y does not exceed 5, R6 is methyl or ethyl and R7 is a C1-4 alkyl group, the relative proportions of diester and polyester being such that the blend has a viscosity of 3-30 cs./210 DEG F. The preferred diesters have the formula R4OOCR5COOR4, where R5 is a C4-14 alkylene group and the R4's are C4-18 alkyl groups, preferably branched-chain, examples being di-(2-ethylhexyl) sebacate; di-(3 : 5 : 5-trimethylhexyl) sebacate; 2 - ethylhexyl - (3 : 5 : 5 - trimethylhexyl) sebacate; and mixtures of all three. The preparation of the polyesters is described and claimed in Specification 861,962. The blend may contain an antioxidant, e.g. phenothiazine. Specifications 824,249 and 861,961 also are referred to.ALSO:A lubricating composition comprises a blend of a liquid aliphatic diester of a saturated aliphatic dicarboxylic acid, and a polyester, soluble in the diester and having the general formula ROOCR1COO(R2OOCR1COO)nR . . .
