Abstract
Methods for reducing or eliminating static electric charges on resins by adding to the resins an effective amount of at least one substituted ammonium salt of an alkylbenzene sulfonic acid, the salt having the formula: ##STR1## wherein R is a straight or branched chain alkyl group having from 10 to 14 carbon atoms, R.sub.1 is hydroxyethyl or an alkyl group having from one to six carbon atoms, R.sub.2 and R.sub.3 are the same or different and are hydroxyethyl, an alkyl group having from one to six carbon atoms, or hydrogen, and R.sub.4 is hydrogen or an alkyl group having from one to six carbon atoms, together with resins so produced and compositions additionally containing fatty acids for such use.
