This invention concerns a process for preparing a sulfurized olefin containing reduced amounts of thiones using a low molecular weight hydrocarbon to precipitate the thiones from the sulfurized olefin.

Sulfurized olefin composition and its method of preparation

An oil-soluble reaction product of phosphorus-, low molecular weight basic nitrogen-, and optional boron-containing compounds is provided. This reaction product can solubilize significantly more phosphorus and boron per weight of compound than other known compounds and is used as an antiwear, antioxidant, and extreme pressure additive in lubrication oils.

Low molecular weight basic nitrogen-containing reaction products as

This invention provides an oil-soluble complex of an oil-insoluble phosphorus-containing acid and an alcohol. This complex is a useful antiwear additive in lubricating oils, particularly automatic transmission fluids.

Oil soluble complexes of phosphorus-containing acids useful as

Non liquid-crystalline esterphenol-capped liquid polymer and polyol compositions in combination with an amino crosslinking agent endow coating compositions containing them with the ability of providing films having superior properties. The esterphenol-capped polymers and polyols can be prepared by direct esterification of hydroxybenzoic acid without its decarboxylation.

Process for preparing phenol-functional polymer

An oil-soluble reaction product of at least one nitrogen-containing compound, at least one phosphorus-containing compound, and at least one mono- or di-sulfide-containing alkanol is provided, which improves friction and/or wear performance of a lubrication oil.

Liquid polymer and polyol compositions, and process for preparing

The present invention is directed towards a mixture of phenol terminated diesters and an amino crosslinking agent. The diesters are characterized by a structure consisting of ##STR1## wherein R is an aliphatic divalent hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, provided however that R contains at least about 8 carbon atoms when n is 0 and p is 0, R.sub.1 is an aliphatic or cycloaliphatic hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, R.sub.2 is a aliphatic, aromatic or a mixture of aliphatic and aromatic hydrocarbon radicals having from 2 to 40 carbon atoms, A is divalent aromatic radical selected from the group consisting of phenylene, naphthylene or bis phenylene, p is 0 or 1, n is 0 or an integer ranging from 1 to about 40, provided however, that p is 0 when n is 0 and p is 1 when n is an integer and ##STR2## wherein q is an integer ranging from 1 to about 40, n is 0 or an integer ranging from 1 to about 40 and A, R.sub.1 and R.sub.2 are as defined above.

Phenol terminated diester compositions derived from dicarboxylic acids,

The present invention is directed towards a process for preparing non-liquid crystalline phenol-terminated diester compositions characterized by the structure of formula 1: ##STR1## wherein R is an aliphatic divalent hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, provided however that R contains at least about 8 carbon atoms when n is 0 and p is 0, R.sub.1 is an aliphatic or cycloaliphatic hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, R.sub.2 is an aliphatic, aromatic or a mixture of aliphatic and aromatic hydrocarbon radicals having from 2 to 40 carbon atoms, A is divalent aromatic radical selected from the group consisting of phenylene, naphthylene or his phenylene, p is 0 or 1, n is 0 or an integer ranging from 1 to about 40, provided however, that p is 0 when n is 0 and p is 1 when n is an integer. The invention is also directed to a single stage direct esterification or multi stage esterification processes for producing the aforementioned diesters of formula 1 either with or without the use of esterification catalysts, and is particularly directed to such processes for preparing diesters of reduced color using a low temperature process in combination with catalyst systems containing a phosphorous acid or derivative thereof.

Phenol terminated diester compositions derived from discarboxylic acids,

The present invention is directed towards non-liquid crystalline phenol-terminated diester compositions which may be liquids or solids and crosslinkable formulations containing a mixture of the phenol terminated diesters and an amino crosslinking agent. These diesters are characterized by the structure of formula 1: ##STR1## wherein R is an aliphatic divalent hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, provided however that R contains at least about 8 carbon atoms when n is 0 and p is 0, R.sub.1 is an aliphatic or cycloaliphatic hydrocarbon radical containing 2 to 40 carbon atoms or a mixture of such radicals, R.sub.2 is an aliphatic, aromatic or a mixture of aliphatic and aromatic hydrocarbon radicals having from 2 to 40 carbon atoms, A is divalent aromatic radical selected from the group consisting of phenylene, naphthylene or bis phenylene, p is 0 or 1, n is 0 or an integer ranging from 1 to about 40, provided however, that p is 0 when n is 0 and p is 1 when n is an integer.

According to one aspect of the present invention, an improved method for preparing acrylic copolymer resins is provided in which the polymerization solvent includes an internal olefin. The monomers comprise hydroxy-substituted alkyl (meth)acrylates, and non-hydroxy substituted alky (meth)acrylates, and the process provides an improved method for forming low molecular weight acrylic resins useful as components in high solids acrylic coatings suitable for electrostatic spraying. The polymerization solvent can remain in the resin to become the solvent employed in the higher solids coating containing the thus-forming acrylic resins and provides surprisingly improved electrical resistivity and color decreased over previously used polymerization solvents, and has good compatibility with the acrylic monomer/resin system.

Solvent mixture for production of high solids acrylic coating resins
