Abstract: The invention provides a lubricating composition containing (a) 0.001 wt % to 15 wt % of a polymer with radial or star architecture; (b) an overbased detergent; (c) a dispersant; and (d) an oil of lubricating viscosity. The invention further provides a method for lubricating a mechanical device with the lubricating composition.

Abstract: The present invention relates to a graft polymer of (a) a polyalphaolefin having a weight average molecular weight of less than 15000 and a polydispersity of 1.1 to 10; (b) a nitrogenous, ethylenically unsaturated, aliphatic or aromatic, graftable monomer having from 2 to about 50 carbon atoms; and (c) an organo-metallic compound selected from organo-molybdenum, organo-titanium, organo-manganese compounds and mixtures thereof; a process for making the graft polymer; and a lubricating oil composition comprising a major amount of a base oil and a minor amount of the graft polymer.

Abstract: A composition of matter resistant to foaming comprising a hydrocarbon oil and an acrylate copolymer dispersed in the said hydrocarbon oil, which acrylated copolymer contains at last one polymerised fluorinated (meth)acrylate monomer wherein not more than three neighbouring carbon atoms in the said fluorinated (meth)acrylate monomer carry one or more fluorine substituents.

Abstract: A two-cycle engine lubricant comprising from about 10% to about 30% low ash detergent inhibitor; from about 10% to about 45% bio-based ester selected from the group consisting of castor oil, a synthetic polyol-based ester and mixtures thereof; from about 14% to about 37% polyalphaolefin; from about 7% to about 18% synthetic ester; from 2% to about 10% surfactant; and from about 2% to about 5% pour point depressant; by weight of the lubricant. Optionally, the subject two-cycle lubricant can also comprise up to about 20 weight percent solvent, such as Stoddard solvent, to improve miscibility of the lubricant with gasoline fuel. The subject lubricant can be pre-packaged with gasoline for use with small engines not equipped for direct lubricant injection. A method for making the subject lubricant composition so as to resist subsequent separation of the components into layers is also disclosed.

Abstract: A process for the preparation of CNSL phenoxy carboxylic acid derivatives for use as an additive in a lubricant composition so as to impart improved rust inhibiting properties, including the steps of (a) partially hydrogenating distilled technical cashew nut shell liquid with palladium or nickel or platinum catalyst; to hydrogenate the olefinic chain; (b) reacting cashew nut shell liquid or partially hydrogenated technical cashew nut shell liquid with halogeno carboxylic acid derivatives to obtain unpolymerized cashew nut shell liquid phenoxy carboxylic acid derivatives, the reaction being carried out at a temperature ranging from 20 to 140° C. A lubricant containing a major proportion of a material selected from the group consisting of an oil of lubricating viscosity and a grease; and remainder an additive including CNSL phenoxy carboxylic acid derivative prepared by the foregoing process.
