  • Publication number: 20040118035
    Abstract: This invention is directed to a catalyst and an associated process for polymerizing olefins or olefin-containing compounds, to corresponding olefin polymers, to derivatives of the olefin polymers, and to lubricant and fuel compositions that include the olefin polymers or their derivatives. The polymerization catalyst is a metal complex and optional cocatalyst where the metal complex is formed from a bidentate ligand having a nitrogen coordinating group and a second coordinating group selected from oxygen, sulfur, selenium and tellurium groups and a metal compound where the metal is a transition metal, boron, aluminum, germanium or tin. Highly branched and reactive ethylene polymers are formed from the catalyst and process of the present invention. The ethylene polymers and their derivatives are useful in various applications including as performance additives in lubricants and fuels.

  • Publication number: 20040014614
    Abstract: A lubricant additive gel formed by the gellation of two or more lubricant additives for the slow release of the additive components into a fluid. The lubricant additive gel slowly releases into its component lubricant additives when contacted with the fluid such as an oil thereby serving as a lubricant fluid such as an oil thereby.

  • Patent number: 6514297
    Abstract: An improved detergent for use in hydrocarbon fuels comprising the composition produced by mixing (1) the Mannich reaction product of a polyisobutene-substituted phenol, (preferably, where the polyisobutene from which the substituted phenol is derived contains at least 70% terminal olefinic double bonds of the vinylidene type); an aldehyde; and an amine, preferably, ethylene diamine; and (2) a compound selected from the group consisting of an alkylbenzene sulfonic acid, an alkylnapthalene sulfonic acid, acetylaetone and mixtures thereof. Preferably, the alkylbenzene and alkylnapthalene sulfonic acid is selected to be a (C6 to C18) alkylbenzene sulfonic acid/napthalene sulfonic acid, especially preferred being dodecylbenzene sulfonic acid.
