ABSTRACT:
A quaternary onium aromatic sulfonate represented by the formula:wherein each R1independently 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; G1is an aromatic group; E comprises a bis(carbonyloxyalkyl) polydiorganosiloxane, a bis(carbonyloxyaryl) polydiorganosiloxane, and an ether linkage; each Y1independently 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 G1available 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.
