Abstract: An electrorheological fluid is prepared from a hydrophobic liquid medium and a dispersed particulate phase of (i) a polar solid material which is capable of exhibiting electrorheological activity in the presence of a low molecular weight polar material and (ii) a non-cellulosic polymeric material having a solubility parameter of about 15 to about 50 (MPa) and exhibiting substantially no electrorheological activity in the absence of a low molecular weight polar material. The fluid optionally contains a low molecular weight polar activator. The fluid has good electrorheological performance over a broad temperature range.

Abstract: A method of preparing boron-containing compositions is described which comprises reacting at least one hydroxy-substituted ester, amide or imide with a boron compound. Such boron-containing compositions are useful in lubricating oils and provide the lubricating oils with anti-wear and/or friction-reducing properties. The boron-containing compositions also are useful in fuel compositions.

Abstract: 2594R/B Title: ELECTRORHEOLOGICAL FLUIDS CONTAINING ELECTRONI CALLY CONDUCTIYE POLYMERS Non-aqueous electrorheological fluids are described which comprise a major amount of a hydrophobic liquid phase and a minor amount of a dispersed particulate phase comprising conductive polymers selected from the group consisting of polypyrroles, polyphenylenes, polyacetylenes, polyvinylpyridines, polyvinylpyrrolidones, poly(substituted anilines), polyvinylidene halides, polyphenothiazines and polyimidazoles. The electrorheological fluids prepared in accordance with the present invention are useful in a variety of applicationsincluding flotational coupling devices such as clutches for automobiles or industrial motors, transmissions, brakes or tension control devices; and linear damping devices such as shock absorbers, engine mounts and hydraulic actuators.

Abstract: Non-aqueous electrorheological fluids are described which comprise a major amount of a hydrophobic liquid phase and a minor amount of a dispersed particulate phase of a polyaniline prepared by polymerizing aniline in the presence of an oxidizing agent and from about 0.1 to about 1.6 moles of an acid per mole of aniline to form an acid salt of polyaniline, and thereafter treating the acid salt with a base. The polyanilines may be prepared from aniline or from mixtures of aniline and other monomers such as pyrroles, vinyl pyridines, vinyl pyrrolidones, thiophenes, vinylidene halides, phenothiazines, imidazolines, N-phenyl-p-phenylene diamines or mixtures thereof. The electrorheological fluids prepared in accordance with the present invention are useful in a variety of applications including flotational coupling devices such as clutches for automobiles or industrial motors, transmissions, brakes or tension control devices; and linear damping devices such as shock absorbers, engine mounts and hydraulic actuators.
