Abstract
A hydrocarbon oxidate composition which comprises the reaction product of (a) a hydrocarbon oxidate, as described herein, or the metal salt thereof, with (b) a polyamine, as described herein, and (c) at least one copolymer of an olefin and a comonomer selected from (i) an unsaturated carboxylic acid; or (ii) a vinyl ester of a saturated carboxylic acid, wherein the hydrocarbon oxidate composition comprises a wax oxidate, a petrolatum oxidate or mixtures thereof and has a very high viscosity, increased molecular weight and sinewy characteristics and is useful as a lubricant, grease, or protective coating.
Claims89
A hydrocarbon oxidate composition having a sinewy or film-forming characteristic comprising the reaction product of:
- (a) a hydrocarbon oxidate, with
- (b) a polyamine containing at least two amino groups, each group having at least one active hydrogen atom;
- and
- (c) at least one copolymer of an olefin and a comonomer selected from (i) an unsaturated carboxylic acid;
- or (ii) a vinyl ester of a saturated carboxylic acid;
- or the metal salt of said reaction product.
A method for altering the characteristics of hydrocarbon oxidate or the metal salts thereof comprising forming the reaction product of:
- (a) a hydrocarbon oxidate, with
- (b) a polyamine having at least two amino groups, each group having at least one active hydrogen atom;
- and
- (c) at least one copolymer of an olefin and a comonomer selected from an (i) unsaturated carboxylic acid;
- or (ii) a vinyl ester of a saturated carboyxlic acid;
- or a metal salt of said reaction product, by reacting, in any order:
- said oxidate (a);
- with
- said polyamine (b);
- and
- said copolymer (c);
- if necessary, forming said metal salt prior to or subsequent to reacting components (a), (b) and (c).
A method of producing a hydrocarbon oxidate composition comprising reacting simultaneously or in any order:
- (a) a hydrocarbon oxidate, with
- (b) a polyamine having at least two amino groups, each group having at least one active hydrogen atom, and
- (c) at least one copolymer of an olefin and comonomer selected from an (i) unsaturated carboxylic acid, or (ii) a vinyl ester of a saturated carboxylic acid.
A method of producing a metal salt of a hydrocarbon oxidate composition comprising reacting simultaneously or in any order:
- (a) a hydrocarbon oxidate, with
- (b) a polyamine having at least two amino groups, each group having at least one active hydrogen atom,
- (c) at least one copolymer of an olefin and a comonomer selected from (i) an unsaturated carboxylic acid;
- or (ii) a vinyl ester of a saturated carboxylic acid, and
- (d) a metal salt forming compound.
