    摘要: The present invention is based on the discovery that viscosification agents selected from sulfonated and neutralized sulfonated ionomers can be readily incorporated into oil-based drilling muds in the form of an oil soluble concentrate containing the polymer. Thus, one embodiment of the present invention provides an additive concentrate for oil-based drilling muds comprising a drilling oil, especially a low toxicity oil, and from about 5 gm to about 20 gm of sulfonated or neutralized sulfonated polymer per 100 gm of oil. Indeed, oil solutions obtained from the sulfonated and neutralized sulfonated polymers used as viscosification agents are readily incorporated into drilling mud formulations.

    摘要: The present invention relates to a process for the encapsulation of a solid substrate with a neutralized sulfonated polymer, which comprises the steps of: (a) forming a solution of a non-conjugated, diene polymer in a solvent selected from the group consisting of aliphatic, aromatic hydrocarbons and mixtures thereof; (b) contacting the solution of the unsaturated polymer with a sulfonating agent at a sufficient temperature and for a sufficient period of time to form a solution of a sulfonated polymer containing free acid; (c) forming a solution of a base selected from the group consisting of alkali metal hydroxides and mixtures thereof in a mixtrue of an aliphatic alcohol and a hydrocarbon, the hydrocarbon being selected from the group consisting of aliphatic and aromatic hydrocarbons and mixtures thereof; (d) adding the solution of base to the solution of sulfonated polymer in an amount sufficient to neutralize the polymer and the free acid, thereby forming a coating solution; (e) contacting the solid substrate with the coating solution while removing the solvent therefrom, thereby forming an encapsulated substrate. In a preferred embodiment, the solvent removed during step (e) is recovered and distilled to separate the solvent into at least two fractions, a fraction containing substantially hydrocarbon and an alcohol containing fraction. The separated solvents are then recycled to dissolve the polymer in step (a) and to dissolve the base in step (c).

    摘要: A method, composition and filter for reducing the presence of sludge or varnish precursors in a lubricating oil circulating within an internal combustion engine. The lubricating oil containing sludge or varnish precursors is contacted with discrete particles of an oil insoluble, oil wettable compound having an antioxidant functional group and/or a dispersant functional group, which are capable of complexing with sludge or varnish precursors. Preferably the compounds comprises a crosslinked amine having ethylene amine functionality. The starting polyethylene amines have a number average molecular weight in the range of about 100 to about 60,000, preferably 200 to 250 and are crosslinked with a silicon oxide, silane, silicate, epoxide, quinone, or phenol-formaldehyde crosslinking agent. The particles are encaged within a one or two stage oil filter together with filtering media such as chemically active filter media, physically active filter media and inactive filter media.

    摘要: An oil based drilling mud is viscosified with a maleated ethylene-propylene elastomers. The elastomers are preferably EPM copolymers or EPDM terpolymers. The concentration of the maleic anhydride grafted to the copolymer or terpolymer backbone ranges from 0.01 to 5 wt %, preferably 0.1 to 2.0 wt %. The maleated elastomers are far more effective oil mud viscosifiers than the organophilic clays presently used.
