The disclosed technology relates to a dispersant composition comprising the reaction product of a polyolefin acylating agent and a polyamine having a sterically hindered head group. In addition, the technology relates to lubricating compositions containing the dispersant composition and an oil of lubricating viscosity, as well as methods of employing the lubricating composition in an engine and engine oils. Lubricating oils containing the dispersants of the disclosed technology simultaneously achieves seal compatibility, wear, deposit, varnish and corrosion control while also maintaining fuel economy performance over a broad temperature range.

The disclosed technology relates to a novel coupled 6-amino uracil derivative, and the use of the coupled 6-amino uracil derivative as a stabilizer in halogen containing polymer compounds. In particular, the disclosed technology relates to the use of a coupled 6-amino uracil derivative as a stabilizer in vinyl chloride compounds, such as, for example, chlorinated polyvinyl chloride (CPVC) compounds.

A lubricating composition includes an oil of lubricating viscosity and an N-substituted hydroxyaromatic succinimide or a salt thereof.

Hydroxyaromatic succinimide detergents for lubricating compositions

An acylated hydrocarbon polymer is aminated by reacting a primary or secondary aromatic amine which is solid at room temperature with an acyl group of the polymer, by: supplying a melt of the acylated polymer; supplying a solution of the aromatic amine in a polar aprotic solvent which has a boiling point of at least about 15&#xb0; C., a melting point below about 40&#xb0; C., and a dielectric constant of at least about 5&#xb0; at 25&#xb0; C.; mixing the solution at 140&#xb0; C. to 185&#xb0; C.; and cooling the resulting amine-reacted polymer with a liquid while retaining the polar aprotic solvent in the polymer.

The disclosed technology relates to a dispersant composition comprising the reaction product of a polyolefin acylating agent and an amine terminated or hydroxyl terminated polyether. In addition, the technology relates to lubricating compositions containing the dispersant composition and an optional synergistic amount of another dispersant, as well as methods of employing the dispersant composition in an engine and engine oils.
