First Claim
1. An antistatic agent of the formula (Q--L--R)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
wherein R1 and R4 independently represent ##STR15## Z being H, Q or ##STR16## wherein Q is as defined above, f being an integer from 1 to 50, R2 represents a C1 -C4 alkyl group, R3 and R5 independently represent a normal or branched, saturated or unsaturated C6 -C22 aliphatic group, Ra represents H or CH3, and A represents an organic or inorganic anion.

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.
