Abstract

There are used as antistatic agents for thermoplastic synthetic resins compounds of the formulae ##STR1## where R and R' are saturated alkyl groups in which the sum of the carbon atoms in the two alkyl groups is 4 to 30 carbon atoms and wherein one of R and R' can be hydrogen, PA1 R.sup.2 is hydrogen, lower alkyl with one to 5 carbon atoms, 2-hydroxyethyl, 2-hydroxypropyl, 2,3-dihydroxypropyl, benzyl o-,m- and/or p-methylbenzyl, o-,m- and/or p-chlorobenzyl, o-,m- and/or p-bromobenzyl, aminoalkyl (C.sub.2 to C.sub.6), preferably aminoalkyl (C.sub.2 and C.sub.3), alkyl (C.sub.1 to C.sub.6)-amino-alkyl (C.sub.2 to C.sub.6), 2-hydroxyethyl-aminoalkyl (C.sub.2 to C.sub.6), 2-hydroxypropyl-aminoalkyl (C.sub.2 to C.sub.6) or 2,3-dihydroxypropyl-aminoalkyl (C.sub.2 to C.sub.6), PA1 R.sup.3 in case the compound is present as the ammonium salt is hydrogen or a lower alkyl group with 1 to 5 carbon atoms, PA1 R.sup.4 is hydrogen or hydroxyl, and PA1 X.sup.- is a monovalent, inorganic or organic acid group or one equivalent of a polybasic inorganic or organic acid group. The antistatic compounds can be premixed with silica to give enhanced antistatic activity.
