The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency. Also provided are means to form stable associative polyelectrolyte complexes in aqueous solutions having R values from about 0.10 to 20, including near stoichiometric R values approaching 1, being the ratio of charged groups present on the component polyelectrolytes employed.

Polyelectrolyte complexes

The present invention generally relates to compositions for use in lubricating oils. In certain aspects, the present invention is generally directed to boroxine compounds having alkyl groups where one or more of the alkyl groups contains at least 8 carbon atoms. Such compounds may present improved hydrolytic stability, compared to other boroxine compounds. Such boroxine compounds may be used, for example, to improve seal compatibility in an engine. Other aspects of the invention are generally directed to systems and methods for making such boroxine compounds, engine oils containing such boroxine compounds, methods of using such boroxine compounds, or the like.

Boroxine based seal compatibility agents

A lubricating oil composition, method for reducing a boundary friction coefficient of a lubricant composition, and method for improving fuel economy. The lubricating oil composition includes a base oil; a) a metal-containing phosphorus antiwear compound in an amount sufficient to provide from about 100 to about 1000 ppm by weight phosphorus based on a total weight of the lubricant composition, and b) a heat bodied vegetable oil, different from the base oil. The base oil is present in the lubricant composition in an amount from about 50 wt. % to about 99 wt. % based on the total weight of the lubricant composition.

Lubricant additives and lubricant compositions having improved frictional characteristics

A lubricant composition, method for reducing a boundary friction coefficient of a lubricant composition, and method for improving fuel economy. The lubricant composition includes a base oil, a) a metal-containing phosphorus antiwear compound in an amount sufficient to provide from about 100 to about 1000 ppm by weight phosphorus based on a total weight of the lubricant composition, and b) an oxygen-polymerized vegetable oil, different from the base oil. The base oil is present in the lubricant composition in an amount from about 50 wt. % to about 99 wt. % based on the total weight of the lubricant composition.

A lubricant additive, method for reducing a boundary friction coefficient of a lubricant composition, and method for improving fuel economy. The additive includes a synergistic mixture of a) a metal-containing phosphorus antiwear compound derived from at least one secondary alcohol in an amount sufficient to provide the lubricant composition with from about 200 to about 1000 ppm by weight phosphorus, and b) a polyol derived from a diol and a mono-ol having a diol to mono-ol molar ratio ranging from about 0.3:1 to about 2.0:1, wherein the diol contains from 6 to 36 carbon atoms and the mono-ol contains from 12 to 16 carbon atoms. The polyol is present in the lubricant additive in an amount sufficient to provide a synergistic reduction in the boundary friction coefficient of the lubricant composition in combination with component (a).
