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, 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), 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, R.sup.4 is hydrogen or hydroxyl, and 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.
以下公式化合物可用作热塑性合成树脂的抗静电剂:##STR1## 其中R和R'是饱和的烷基,两个烷基中碳原子的总和为4到30个碳原子,其中一个R和R'可以是氢,R.sup.2是氢、含有1到5个碳原子的低烷基、2-羟基乙基、2-羟基丙基、2,3-二羟基丙基、苯甲基o-、m-和/或p-甲基苯甲基、o-、m-和/或p-氯苯甲基、o-、m-和/或p-溴苯甲基、氨基烷基(C.sub.2到C.sub.6),优选氨基烷基(C.sub.2和C.sub.3)、烷基(C.sub.1到C.sub.6)-氨基-烷基(C.sub.2到C.sub.6)、2-羟基乙基-氨基烷基(C.sub.2到C.sub.6)、2-羟基丙基-氨基烷基(C.sub.2到C.sub.6)或2,3-二羟基丙基-氨基烷基(C.sub.2到C.sub.6),在化合物以铵盐形式存在时,R.sup.3是氢或含有1到5个碳原子的低烷基,R.sup.4是氢或羟基,X.sup.-是一价的无机或有机酸基或一个多元无机或有机酸基的一个当量。这些抗静电化合物可以与二氧化硅预混以提高抗静电活性。
