    Abstract: This invention relates to a composition, comprising: (A) a compound represented by the formula wherein in Formula (A-I), R , R , R and R are independently hydrocarbyl groups, X and X are independently O or S, and n is zero to 3; and (B) an acylated nitrogen-containing compound having a substituent of at least 10 aliphatic carbon atoms. In one embodiment, the inventive composition further comprises (C) a second phosphorus compound other than (A), said second phosphorus compound being a phosphorus acid, phosphorus acid ester, phosphorus acid salt, or derivative thereof. In one embodiment, the inventive composition further comprises (D) an alkali or alkaline earth metal salt of an organic sulfur acid, carboxylic acid or phenol. In one embodiment, the inventive composition further comprises (E) a thiocarbamate. These compositions are useful in providing lubricating compositions and functional fluids with enhanced antiwear properties.

    Abstract: A nitrogen-containing ester derived from a carboxy-containing interpolymer having a reduced specific viscosity (RSV) of from about 0.05 to about 2, said interpolymer being derived from at least two monomers, (i) one of said monomers being at least one of an aliphatic olefin containing from 2 to about 30 carbon atoms and a vinyl aromatic monomer and (ii) the other of said monomers being at least one alpha, beta-unsaturated acylating agent, said ester being characterized by the presence within its polymeric structure of each of the following groups which are derived from the carboxy groups of said interpolymer: (A) from about 20 to about 70 mole % based on moles of carboxyl groups in said interpolymer, of ester groups containing from about 13 to about 19 carbon atoms; (B) from about 80 to about 30 mole %, based on moles of carboxyl groups in said interpolymer, of ester groups containing from about 8 to about 12 carbon atoms, optionally; (C) up to about 20 mole %, based on moles of carboxyl groups in said interpolymer, of ester groups containing from 2 to 7 carbon atoms; wherein from about 93 to about 97% of the carboxy groups derived from the carboxy-containing interpolymer are ester groups, the balance of the carboxy groups comprising residual carboxylic acid or anhydride groups which are then (D) reacted with at least one amino compound having an average of from 1 to about 1.1 primary or secondary amino groups, to convert from about 5 up to less than 50% of the carboxylic acid or anhydride groups to carbonyl-amino groups, with the unreacted carboxylic acid or anhydride groups remaining as (E) residual carboxylic acid or anhydride groups. Additive concentrates and lubricating oil compositions are also disclosed.
