Abstract: The invention is a catalyst system including a monocyclopentadienyl titanium compound, where the monocyclopentadienyl group is bonded to a silylene-imido moiety which is further bonded to the titanium atom, and an alumoxane component which is highly productive for polymerizing ethylene and &agr;-olefins to produce a high molecular weight ethylene-&agr;-olefin copolymer having a high content of &agr;-olefin.

Abstract: Polyolefin/filler breathable films may be produced by machine or transverse direction orientation using interdigitating grooved rollers. Biaxial orientation to similarly produce breathable films may be accomplished by the same method. By heating the rollers, the breathability of the film is increased without increasing the depth of engagement of the interdigitating rollers.

Abstract: Alcohols suitable for plasticizer ester manufacture and acids are made by cofeeding olefins to oxonation, aldolizing the resulting aldehyde and hydrogenating the resulting unsaturated aldehydes, optionally dehydrating a part of the alcohol thereby made and returning the resulting olefin to oxonation, or oxidizing the aldehydes.

Abstract: The lubricity of low sulfur content middle distillate fuel oil boiling over a temperature range of 100°C. to 500°C. is enhanced by incorporation of a heavy fuel component having hydrocarbon components resulting from distillation of a crude oil, whereby the incorporation of the heavy fuel component increases at least one of (a) the 50% distillation temperature, and (b) the polynuclear aromatic content of the composition, and wherein the composition gives a wear scar diameter, as measured by the HFRR test at 60°C., of at most 500 &mgr;m.

Abstract: The antiwear performance of power transmitting fluids, particularly continuously variable transmission fluids, is improved by incorporating an additive combination of amine phosphates, organic polysulfides, zinc salts of phosphorothioic acid esters and optionally a friction modifier.

Abstract: Specific substituted aromatic ester compounds are useful as lubricity additives for middle distillate fuel oils.

Abstract: A process for rendering films, film composites, and articles made therefrom less resistant to passage of water vapor by passing a filled precursor film or film composite through the nip of interdigitating grooved rollers. The films or film composites are generally formed using a precursor film of a film forming polyolefin or polyolefin blend, with a relatively high filler loading and optionally an elastomer. A process is disclosed for making diapers or other disposable items where a relatively high water vapor is coupled with a resistance to liquid strikethrough. In one embodiment of the invention, the interdigitating grooved rollers are maintained in a temperature range of from about 91° F. to about 159° F.

Abstract: A process for reproducibly forming a thermally and oxidatively stable high hydroxyl glycerol di-ester compound which is particularly useful as a lubricant. The glycerol di-ester compound is formed by reacting a glycidyl ester with an excess of a neo acid salt. The di-ester product is produced in a nearly quantitative conversion and is readily recoverable from the reaction mixture via a water wash, vacuum dry, and a mild wiped film evaporator treatment.

Abstract: Reaction products of long chain esters with amines improve the cold flow properties of oils.

Abstract: In the preparation of thermoplastic elastomers by hydrosilylation crosslinking of the elastomeric component, the use of an elastomer containing a non-conjugated diene and having a Mooney viscosity within the MST range of 45 to 100 provides products with a high level of crosslinking and an improved combination of physical properties. This improvement is obtained even at low concentrations of hydrosilylation catalyst.
