Heat stable quaternized lactams having oxylated sulfur anions

A quaternized lactam having the formula:

• ##STR21## wherein m is an integer having a value of from 1 to 4;
• R is alkylene having from 3 to 8 carbon atoms and is optionally substituted with C.sub.1 to C.sub.4 alkyl;
• R.sub.1, R.sub.2 and R.sub.3 are each independently selected from the group of alkyl, alkyloxyalkyl, alkyloxyalkenyl, hydroxyalkyl, aryl, aralkyl, alkaryl, alkyl amidoalkyl, alkyl carbamoylalkyl, aryl amido alkyl and aryl carbamoylalkyl radicals, and R.sub.2 and R.sub.3, together with the quaternized nitrogen atom can form a saturated or unsaturated 5 to 10 membered monocyclic ring;
• a 9 to 10 membered bicyclic ring or a 13 to 14 membered tricyclic ring, which rings may contain a carbonyl group and which rings are optionally substituted with lower alkyl, amino or amido, at least one of said rings containing from 1 to 2 heteroatoms selected from the group of nitrogen, sulfur and oxygen, and, where the quaternized nitrogen atom in the heterocyclic structure is doubly bonded to an adjacent ring atom, R.sub.1 represents one bond of said double bond in the heterocyclic structure, otherwise R.sub.1 bonded to the quaternized nitrogen in a heterocyclic structure is any of the aforementioned individual groups for R.sub.1, R.sub.2 and R.sub.3 ;
• said groups R.sub.1, R.sub.2 and R.sub.3 each having from 1 to 30 carbon atoms and at least one of R.sub.1, R.sub.2 and R.sub.3 is a radical having from 8 to 30 carbon atoms when R.sub.2 and R.sub.3 are not part of a heterocyclic moiety;
• and A.sup.- is an anion derived from an oxylated sulfur compound, having the formula:
• R'SO.sub.3.sup.-
• wherein R' is alkyl, alkoxy, phenyl, phenoxy, alkylphenyl, alkylphenoxy, phenylalkyl, phenoxyalkyl, C.sub.12 to C.sub.20 .alpha.-olefin or mixtures thereof and wherein the alkyl moieties of said R' groups contain from 1 to 20 carbon atoms and said R' groups are optionally alkoxylated with from 1 to 20 units of ethyleneoxide and/or propylene oxide.
