| 20080269351 | ALKYLATED HYDROXYAROMATIC COMPOUND SUBSTANTIALLY FREE OF ENDOCRINE DISRUPTIVE CHEMICALS AND METHOD OF MAKING THE SAME - An alkylated hydroxyaromatic compound prepared by reacting at least one hydroxyaromatic compound with a branched olefinic oligomer having from about 20 to about 80 carbon atoms in the presence of a acid catalyst. The alkylated hydroxyaromatic compound has been determined to be substantially free of endocrine disruptive chemicals when the effects were quantified on pubertal development and thyroid function in the intact juvenile female rat. | 10-30-2008 |
| 20090143264 | SULFURIZED METAL ALKYL PHENATE COMPOSITIONS HAVING A LOW ALKYL PHENOL CONTENT - Provided herein are sulfurized metal alkyl phenate compositions having a low alkyl phenol content. The sulfurized metal alkyl phenate compositions can be prepared by reacting a phenol compound of Formula (I) disclosed herein with an aldehyde to form a phenolic resin of Formula (II) disclosed herein and then by reacting the phenolic resin simultaneously with a metal base and a first sulfurizing agent. The sulfurized metal alkyl phenate compositions and the overbased sulfurized metal alkyl phenate compositions disclosed herein may be used as detergents for formulating lubricating oil compositions. The lubricating oil compositions disclosed herein have a reduced amount of the free phenol compound and a salt thereof. | 06-04-2009 |
| 20090258803 | COPOLYMERS MADE WITH QUASI-LIVING POLYOLEFINS AND UNSATURATED ACIDIC REAGENTS, DISPERSANTS USING SAME, AND METHODS OF MAKING SAME - Copolymers made with quasi-living polyolefins and unsaturated acidic reactants, dispersants using same, and methods of making same are provided. Under one aspect, a copolymer of an unsaturated acidic reactant and high molecular weight polyolefin, wherein the polyolefin comprises an exo-olefin terminated quasi-living polymeric product, is provided. The quasi-living polymeric product is formed, e.g., by forming a quasi-living cationic polyolefin under suitable quasi-living conditions, and contacting the cationic polyolefin with an agent selected to convert the cationic polyolefin to the exo-olefin terminated quasi-living polymeric product. The cationic polyolefin can be formed, e.g., by one of (a) contacting a cationically polymerizable monomer with an initiator, in the presence of a Lewis acid; (b) ionizing a tert-halide terminated polyolefin with a Lewis acid; (c) contacting a preformed polyolefin with a Lewis acid; or (d) contacting a cationically polymerizable monomer with an inifer carrying at least two tertiary halogens under cationic polymerization conditions. | 10-15-2009 |
| 20100016191 | Copolymers Made With Allyl-Terminated Polyolefins And Unsaturated Acidic Reagents, Dispersants Using Same, and Methods of Making Same - Copolymers made with allyl-terminated polyolefins and unsaturated acidic reactants, dispersants using same, and methods of making same are provided. Under one aspect, a copolymer of an unsaturated acidic reactant and high molecular weight polyolefin, wherein the polyolefin comprises an allyl-terminated polymeric product, is provided. The allyl-terminated polymeric product is formed, e.g., by forming a quasi-living tert-halide terminated polyolefin under suitable quasi-living conditions, and contacting the tert-halide terminated polyolefin with an allylsilane compound and a Lewis acid. In some embodiments, the allylsilane compound includes allyltrimethylsilane. | 01-21-2010 |

| 20100160194 | POST-TREATED ADDITIVE COMPOSITION AND METHOD OF MAKING THE SAME - An oil-soluble lubricating oil additive composition prepared by the process which comprises reacting (A) reacting a copolymer of an (i) an unsaturated acidic reagent; and (ii) a mono-olefin, with at least one linking hydrocarbyl di-primary amine, thereby producing a hybrid succinic anhydride copolymer having from about 10% to about 90% unreacted anhydride groups; and subsequently (B) reacting the hybrid succinic anhydride copolymer with a second amine compound, thereby producing the succinimide; and (C) reacting the succinimide with at least one post-treating agent selected from a cyclic carbonate, a linear mono-carbonate, a linear poly-carbonate, an aromatic polycarboxylic acid, an aromatic polycarboxylic anhydride, an aromatic polycarboxylic acid ester, or mixtures thereof. | 06-24-2010 |
| 20100249001 | AMINE-TERMINATED TELECHELIC POLYMERS AND PRECURSORS THERETO AND METHODS FOR THEIR PREPARATION - Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with a functionalized N-substituted pyrrole to thereby introduce the functionalized N-substituted pyrrole at the terminal reactive polymer chain end(s). A method is also disclosed whereby the N-substituent may be derivatized to a basic amine containing functional group. Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is substituted at the 2 and 3 position of the N-substituted pyrrole. | 09-30-2010 |
| 20100311915 | METHOD FOR PREPARATION OF POLYOLEFINS CONTAINING EXO-OLEFIN CHAIN ENDS - The present invention is directed to a method for preparation of polyolefins containing exo-olefin chain ends. The method involves quenching a cationic quasi-living polyolefin polymer system with a nitrogen-containing five-membered aromatic ring having at least two hydrocarbyl substituent compounds attached to the ring. | 12-09-2010 |
| 20110118160 | Alkylated hydroxyaromatic compound substantially free of endocrine disruptive chemicals - An alkylated hydroxyaromatic compound is disclosed which is prepared by reacting at least one hydroxyaromatic compound with at least one branched olefinic propylene oligomer having from about 20 to about 80 carbon atoms in the presence of an acid catalyst, wherein the at least one branched olefinic propylene oligomer is substantially free of any vinylidene content.
