Abstract:
A lubricant composition of (a) an oil of lubricating viscosity; (b) a poly(meth)acrylate ester polymer comprising 0.5 to 5 weight percent of amine nitrogen-containing dispersant monomer units and (c) an esterified copolymer with a backbone comprising units derived from (i) an α-olefin monomer of at least about 6 carbon atoms, (ii) an ethylenically unsaturated carboxylic acid or derivative thereof, further containing nitrogen functionality in groups pendant from the copolymer backbone, provides a good combination of seal performance and oxidation resistance.

Claim (Index 21):
A method for improving the fluoroelastomer seals compatibility of a lubricant composition comprising (a) an oil of lubricating viscosity and (b) a poly(meth)acrylate ester polymer comprising (i) about 50 to about 99.5 weight percent ester monomer units wherein the alcohol-derived component of the ester monomer contains 6 to about 24 carbon atoms and (ii) about 0.5 to about 5 weight percent of amine nitrogen-containing dispersant monomer units, said polymer having a nitrogen content of about 0.05 to about 1.0 weight percent;\n said method comprising including in said lubricant composition: (c) an esterified copolymer with a backbone comprising units derived from (i) an \u03b1-olefin monomer of at least about 6 carbon atoms and (ii) an ethylenically unsaturated carboxylic acid or derivative thereof, wherein the mole ratio of (i) \u03b1-olefin monomer to (ii) carboxylic acid or derivative monomer is about 1:3 to about 3:1, said copolymer further containing nitrogen functionality in groups pendant from the copolymer backbone, said pendant groups being represented by the structure where X represents the point of attachment to the copolymer backbone through an ester or amide or imide linkage, Hy represents a hydrocarbylene group of 1 to about 6 (or 1 to 4, or 2) carbon atoms; Q is \u2014O\u2014 or \u2014NR 1 \u2014 or \u2014CR 2 R 3 \u2014; each of R 1 , R 2 , and R 3  is independently hydrogen or a C 1  to C 6  alkyl group; R\u2032 and R\u2033 are each independently H or alkyl groups or are alkylene groups joined together to form, with the N\u2014C(O)-Q structure, a 5- or 6-membered ring.
