Lubricant compositions comprising (I), a viscosity improving agent, (II) a boron-containing dispersant, and (III) an ester of an aromatic carboxylic acid having six to ten carbon atoms in the aromatic nucleus and a total of 6 to 40 aliphatic and alicyclic carbon atoms as well as additive concentrates for making such lubricant compositions are disclosed. Preferably, (I) is a carboxy-containing interpolymer in which some carboxy radicals are esterified and the remaining carboxy radicals are neutralized with an amino compound and (II) is a borated, acylated polyamino compound, having an acyl group containing at least 50 carbon atoms. These lubricant compositions are useful as automatic transmission fluids and the like.

Lubricant compositions containing boron dispersant, VI improver, and

Bis-amidoalkanesulfonic acids and their salts find use in applications where amides and sulfonic compounds are useful. Bis-acrylamides and the like are polymerizable monomers whose polymers are useful as gelling agents for aqueous systems, as well as for the preparation of fibers, plastics, resins, etc.
