Abstract: An abrasive article comprises abrasive particles bonded to microporous material wherein the microporous material comprises (a) a matrix consisting essentially of thermoplastic organic polymer, (b) a large proportion of finely divided water-insoluble siliceous filler, and (c) a large void volume.

Abstract: A lubricating composition for use in slicing or cutting silicon wafers. The composition includes a soap, a phosphorous containing compound, and an ethylene oxide-propylene oxide polymer. The phosphorous compound is a low temperature, extreme pressure lubricant. The ethylene oxide propylene oxide polymer is a high temperature, extreme pressure lubricant. Suitable soaps include C6-C18 fatty acids reacted with triethanolamine or aminoethanolamine. Additionally, biocides or fungicides may be added. Also an antifoam and a complexing aid such as EDTA may be used.

Abstract: Disclosed is a grease composition comprising a major proportion of a grease, a hydroxy-containing soap thickener and a minor amount of a boronated oxazoline compound. The hydroxy-containing soap thickener and boronated oxazoline compound are each added in amounts sufficient to increase the dropping point of the grease an appreciable amount. Generally this can be an increase of at least 15.degree. F. and could be as great as 200.degree. F. to 250.degree. F. or more. Sulfur and phosphorus compounds can also be incorporated into the composition.

Abstract: A hydration product is produced from an olefinic feedstock by contacting the olefinic feedstock with water under hydration conditions in the presence as catalysts of a unidimensional medium pore crystalline zeolite, for example Theta-1, ferrierite, ZSM-22, ZSM-23 or NU-10. Theta-1 is the preferred catalyst.
