Abstract
Antistatic agents and their use in processing textiles or formed plastic substrates. The antistatic agent comprises a compound having a fluorocarbon moiety and an ethoxylated quaternary ammonium moiety. The antistatic composition increases the electrolytic conductivity of textile or plastic materials treated therewith, thereby increasing the rate of electrostatic charge dissipation thereof. The coatings remain effective after exposure of the treated substrate to an aqueous environment.

An antistatic agent of the formula (Q--L--R).sub.d --X, wherein Q represents a straight or branched, saturated or unsaturated perfluoroaliphatic radical, L represents a linkage selected from the group consisting of ester, ether, amide or alkylene amine linkages, R represents a straight or branched alkylene-oxyalkylene or a straight or branched alkylene-poly(oxyalkylene) group, and d is 1 or 2, and, when d is 1, X represents at least one quaternary ammonium group of the formula ##STR12## and, optionally, a tertiary amine-forming group of the formula ##STR13## and, when d is 2, X represents a quaternary amine-forming group of the formula ##STR14## and, optionally, a tertiary amine-forming group of the formula
- N--R.sub.5
- wherein R.sub.1 and R.sub.4 independently represent ##STR15## Z being H, Q or ##STR16## wherein Q is as defined above, f being an integer from 1 to 50, R.sub.2 represents a C.sub.1 -C.sub.4 alkyl group, R.sub.3 and R.sub.5 independently represent a normal or branched, saturated or unsaturated C.sub.6 -C.sub.22 aliphatic group, R.sub.a represents H or CH.sub.3, and A represents an organic or inorganic anion.
A composition comprising the product of the reaction between at least one straight or branched, saturated or unsaturated perfluoroaliphatic carboxylic acid and at least one quaternary ammonium compound of the formula ##STR34## wherein R.sub.a represents H or CH.sub.3, g and k may be the same or different and are each integers from 1 to 50, j is an integer from 1 to 4, R.sub.6 represents a straight or branched, saturated or unsaturated C.sub.6 -C.sub.22 aliphatic group, R.sub.b and R.sub.c represent H, straight or branched alkylene primary amine or straight or branched alkylene secondary amine, and A is an organic or inorganic anion, and, optionally, a tertiary amine of the formula ##STR35## wherein R.sub.a, R.sub.b and R.sub.c are as defined above, m and n may be the same or different and are each integers from 1 to 50 which may be the same or different, and R.sub.7 represents a straight or branched, saturated or unsaturated, C.sub.6 -C.sub.22 aliphatic group;
