Polyetheralkanolamine Dispersants
The present invention provides water-soluble products formed by reacting a monofunctional, amine-terminated polyether with a glycidyl ether of a polyol, which products are useful as dispersants in end uses and formulations known to employ dispersants. The invention also provides processes which comprises reacting a monofunctional, amine-terminated polyether with a glycidyl ether of a polyol.
1 ) A composition of matter useful as an dispersing agent, which composition comprises a water-soluble dispersant having the structure:
in which R 1 may be any C 1 -C 100 aliphatic hydrocarbyl group; R 2 may independently be any alkoxylated hydrocarbyl group defined by the structure:
in which R 3 is independently selected from the group consisting of: hydrogen, and any C 1 to about C 24 hydrocarbyl group; X 1 , X 2 , X 3 , X 4 , X 5 , and X 6 in each occurrence are independently selected from the group consisting of: hydrogen, methyl and ethyl, subject to the proviso that at least one of the two X groups that are attached to the same alkoxy unit are hydrogen, p, q, and r may each independently be any integer between zero and about 100, including zero, subject to the proviso that at least one of p, q, and r is not zero; n is any integer between 1 and about 50; and s may be either 0 or 1.
2 ) A composition according to claim 1 further comprising a solvent.
3 ) A composition according to claim 2 wherein said solvent component comprises water.
4 ) A composition according to claim 2 wherein said solvent comprises one or more organic solvents selected from the group consisting of: polyhydric alcohols; glycols; diols; glycol esters; glycol ethers; polyalkyl glycols; lower alkyl ethers of polyhydric alcohols; alcohols having fewer than about 8 carbon atoms per molecule; ketones; ethers; esters; and lactams.
5 ) A composition according to claim 2 wherein said solvent comprises one or more organic solvents selected from the group consisting of: ethylene glycol, propylene glycol; butanediol; pentanediol; glycerol; propylene glycol laurate; polyethylene glycol; ethylene glycol monomethyl ether, ethylene glycol mono-ethyl ether; ethylene glycol mono-butyl ether; alcohols having fewer than about 8 carbon atoms per molecule such as methanol, ethanol, propanol, iso-propanol; acetone; dioxane; ethyl acetate, propyl acetate, tertiary-butyl acetate, and 2-pyrrolidone.
6 ) A composition according to claim 2 wherein the amount of said solvent component present is any amount between about 50% and 99% by weight based on the total weight of said composition.
7 ) A composition of matter which comprises a water-soluble dispersant having the structure:
in which R 1 may be any C 1 -C 100 aliphatic or aromatic hydrocarbyl group; R 2 may be any alkoxylated hydrocarbyl group defined by the structure:
in which R 3 is selected from the group consisting of: hydrogen, and any C 1 to about C 24 hydrocarbyl group; X 1 , X 2 , X 3 , X 4 , X 5 , and X 6 in each occurrence are independently selected from the group consisting of: hydrogen, methyl and ethyl, subject to the proviso that at least one of the two X groups that are attached to the same alkoxy unit are hydrogen, p, q, and r may each independently be any integer between zero and about 100, including zero, subject to the proviso that at least one of p, q, and r is not zero; n is any integer between 2 and about 20; and s may be either 0 or 1.
8 ) A composition according to claim 7 further comprising a solvent.
9 ) A composition according to claim 8 wherein said solvent component comprises water.
10 ) A composition according to claim 8 wherein said solvent comprises one or more organic solvents selected from the group consisting of: polyhydric alcohols; glycols; diols; glycol esters; glycol ethers; polyalkyl glycols; lower alkyl ethers of polyhydric alcohols; alcohols having fewer than about 8 carbon atoms per molecule; ketones; ethers; esters; and lactams.
11 ) A composition according to claim 8 wherein said solvent comprises one or more organic solvents selected from the group consisting of: ethylene glycol, propylene glycol; butanediol; pentanediol; glycerol; propylene glycol laurate; polyethylene glycol; ethylene glycol monomethyl ether, ethylene glycol mono-ethyl ether; ethylene glycol mono-butyl ether; alcohols having fewer than about 8 carbon atoms per molecule such as methanol, ethanol, propanol, iso-propanol; acetone; dioxane; ethyl acetate, propyl acetate, tertiary-butyl acetate and 2-pyrrolidone.
12 ) A composition according to claim 8 wherein the amount of said solvent component present is any amount between about 50% and 99% by weight based on the total weight of said composition.
