[Object] To provide lubricating thermoplastic resin compositions that can give formed articles exhibiting excellent lubricating properties and surface appearance and maintaining the lubricating properties permanently.[Solution] The lubricating thermoplastic resin composition includes an acid-modified copolymer (A) of a monomer mixture including an aromatic vinyl and a vinyl cyanide, the copolymer having a carboxyl group in the molecular chain, and a functionalized lubricant (B) having, in the molecule, a functional group (B1) capable of reacting with the carboxyl group and a lubricating segment (B2) having lubricating properties. The composition may further include a graft copolymer (C) and/or an additional thermoplastic resin (D) other than the acid-modified copolymer (A).

A lubricating composition comprising: (i) from 50% to 99% by weight of base oil; (ii) from 0.01% to 5% by weight of ionic liquid; and (iii) from 0.01% to 10% by weight of additive; wherein the lubricating composition has a pour point of at most −54° C., a flashpoint of at least 246° C. and a kinematic viscosity at 100° C. in the range of from 4.9 to 5.4 mm2/s. The lubricating compositions according to the present invention are suitable for use in turbine engine oils and are useful for reducing the build up of sludge and for reducing coking in the lubricating composition.

This invention relates to addition products of dialkylphosphorodithioic acid, hexachlorocyclopentadiene, or bromotrichloromethane to unsaturated or epoxy fatty acid amides and esters. These products are useful as extreme pressure lubricants and additives.
摘要:
Compositions substituted with iodine, with either bromine or chlorine, and with either alkoxy, acyloxy, or hydroxy groups are prepared by adding a mixture of iodine and either bromine or chlorine or IBr or ICI to alpha-olefins in the presence of alcohols, carboxylic acids, or water. Lubricating compositions useful for lubricating high temperature alloys are prepared by adding such compounds to oils of lubricating viscosity.

HALOGENATED METHYLENEDIPHOSPHONATE ESTERS (7 TO 22 CARBON ATOMS IN EACH ESTER GROUP), HALOGENATED MALONATE ESTERS (4-22 CARBON ATOMS IN EACH ESTER GROUP), AND HALOGENATED PHOSPHONOACETATE ESTERS (8 TO 22 CARBON ATOMS IN EACH ESTER GROUP) ARE DISCLOSED, WHEREIN THE HALOGEN IS PRESENT ON THE BRIDGING CARBON ATOM BETWEEN THE ESTER MOIETIES. THE COMPOUNDS HAVE UTILITY AS EXTREME PRESSURE AND ANTI-WATER ADDITIVES FOR LUBRICANT COMPOSITIONS. ALSO DISCLOSED IS A PROCESS FOR PREPARING SAID HALOGENATED ESTERS BY REACTING THE CORRESPONDING UNHALOGENATED ESTERS WITH HYPOHALITE IONS IN AN AQUEOUS REACTION MEDIUM CONTAINING A WATER-MISCIBLE ORGANIC SOLVENT.
