| 20100285954 | DEHYDROGENATION CATALYST PREPARATION BY DRY IMPREGNATION - The invention relates to a method of preparing a dehydrogenation catalyst comprising a group VIII metal, a group IVA metal and a refractory oxide support. The method comprises stages of preparing the dry impregnation aqueous solution containing said group VIII metal, ammonia, either in solution or in gas form, and a complexing agent. It then comprises stages of aging the aqueous solution, of dry impregnation of the support, of maturing the impregnated support, of drying the impregnated support and of calcining the dried support. | 11-11-2010 |

| 20100298486 | MONOVINYLIDENE AROMATIC POLYMERS CONTAINING NONFUNCTIONALIZED, NONMINERAL OIL - Monovinylidene aromatic polymers, e.g., general purpose polystyrene or high impact polystyrene, are plasticized with a nonfunctionalized, nonmineral oil, e.g., a vegetable oil such as canola oil, cottonseed oil or the like. The mixture of monovinylidene aromatic polymer and oil is typically and preferably free of any significant amount of functionalized nonmineral oil, and it typically contains at least 0.1 weight percent of the nonfunctionalized, nonmineral oil, alone or in combination with a mineral oil, based on the weight of the polymer. The nonmineral oil has an iodine value of less than 120, and a hydroxyl number of less than 20. | 11-25-2010 |

| 20100125122 | PROCESS FOR THE PRODUCTION OF A (CO)POLYMER COMPOSITION BY MEDIATED FREE RADICAL CHAIN GROWTH POLYMERIZATION - The present invention is a multistage process for the preparation of a co)polymer composition. Said process comprises the steps of: i) polymerizing in a first stage a reaction mixture comprising one or more monomer with optionally a rubber, a comonomer, a polymerization initiator, a chain transfer agent, a decomposition catalyst and/or a solvent, in the presence of one or more stable free radical precursor which provides a stable free radical during the polymerization process and/or one or more stable free radical such that the polymerization proceeds via a mediated free radical polymerization mechanism until a partial conversion of monomer(s) to (co)polymer is obtained and ii) polymerizing in a second stage the partially converted reaction mixture under reaction conditions that proceed via a free radical polymerization mechanism to obtain a further degree of conversion of monomer(s) to (co)polymer. | 05-20-2010 |

| 20080255013 | Lubricating Oil Compositions - Use of an oil-soluble hydrocarbyl phenol aldehyde condensate as an antiwear additive in a lubricating oil composition. The oil-soluble hydrocarbyl phenol aldehyde condensate has the following structure: | 10-16-2008 |
| 20090156442 | Lubricant Compositions With Low HTHS for a Given SAE Viscosity Grade - A lubricant composition that exhibits low high temperature high shear viscosity is disclosed. The lubricant composition is made up of a first polymer having a kinematic viscosity ratio less than or equal to 0.25 and a shear stability index (SSI) equal to or greater than 20 percent and base oil having a viscosity index equal to or greater than 120. | 06-18-2009 |
| 20100173811 | ADDITIVES AND LUBRICATING OIL COMPOSITIONS CONTAINING SAME - Para-alkylated substituted diphenylamines are made by catalytically alkylating diphenylamine with a branched-chain alkene, such as propene, oligomer mixture in which the oligomer present in the greatest percentage has 15-24 carbon atoms. The alkylated diphenylamines are useful crankcase lubricant additives such as for reducing piston deposits and engine sludge. | 07-08-2010 |
