Abstract

A quaternary onium aromatic sulfonate represented by the formula: wherein each R 1 independently comprises substituted or unsubstituted, aliphatic or aromatic, hydrocarbyl, carbocyclic or heterocyclic radicals, each X is selected from the group consisting of phosphorus and nitrogen; wherein “a” has a value of 0, 1 or 2, and “b” has a value of 0 or 1 with the proviso that (a+b) is equal to 1 or 2; G 1 is an aromatic group; E comprises a bis(carbonyloxyalkyl) polydiorganosiloxane, a bis (carbonyloxyaryl) polydiorganosiloxane, and an ether linkage; each Y independently comprises hydrogen, a monovalent hydrocarbon group, alkenyl, allyl, halogen, bromine, chlorine; nitro; and OR, wherein R is a monovalent hydrocarbon group; “q” represents any integer from and including zero through the number of positions on G 1 available for substitution; “t” represents an integer equal to at least one; “s” represents an integer equal to either zero or one; and “u” represents any integer including zero; with the proviso that when E is an ether linkage, then X is phosphorus.

Claims (13)

1. An antistatic or antidust composition comprising a melt blend of:

an aromatic sulfonate compound and a thermoplastic polymer, wherein the aromatic sulfonate compound is represented by the formula:

wherein each R 1 independently comprises aliphatic or aromatic, substituted or unsubstituted, carbocyclic or heterocyclic radicals, each X is selected from the group consisting of phosphorus and nitrogen; wherein “a” is 0, 1 or 2, and “b” is 0, 1 or 2 with the proviso that (a+b) is an integer greater than or equal to 1; G 1 is an aromatic group; E comprises a bis(carbonyloxyalkyl) polydiorganosiloxane, a bis(carbonyloxyaryl) polydiorganosiloxane, and-an ether linkage or an ether linkage; each Y 1 independently comprises hydrogen, a monovalent hydrocarbon group, alkenyl, allyl, halogen, nitro; and OR, wherein R is a monovalent hydrocarbon group; “q” represents any integer from and including zero through the number of positions on G 1 available for substitution; “t” represents an integer equal to at least one; “s” represents an integer equal to either zero or one; and “u” represents any integer including zero; with the proviso that when E is an ether linkage, then X is phosphorus.

2. The composition of claim 1 , wherein said aromatic sulfonate compound is about 2.5×10 −3 parts to about 6 parts per 100 parts of the thermoplastic polymer.

3. The composition of claim 1 , wherein said thermoplastic polymer comprises a polycarbonate, polyestercarbonate, polyphenylene sulfide, polyetherimide, polyester, polyphenylene ether, polyphenylene ether/styrene polymer blends, polyamide, polyketone, acrylonitrile-butadiene-styrene copolymer, styrene-acrylonitrile copolymer, polyolefin, blends thereof, and blends thereof with other materials.

4. The composition of claim 1 , wherein the aromatic sulfonate compound is selected from the group of formulas consisting of:

wherein “a” has a value of about zero or one, R 2 can occupy an ortho or a para position on the aromatic ring, and is independently selected from the group consisting of C 6 to C 20 linear and branched alkyl radicals; and

wherein “n” has a value of about 7, and mixtures thereof.

5. A molded or blown article comprising the composition of claim 1 .

6. A coating composition comprising the composition of claim 1 .

7. A film comprising the composition of claim 1 .

8. A fiber comprising the composition of claim 1 .

9. A fabric comprising the fiber of claim 8 .
