Combinations of Antistatic Agents

None of the antistatic agents combine all the properties needed, i.e., antistatic efficiency, heat stability, miscibility with the basic polymer, nontoxicity, hygienic acceptability. The easiest practical answer to this problem is to use mixed antistatic agents showing a synergetic effect. It concerns either the mere mixtures of two or more antistatic agents or the so-called internal mixtures, which means that the same molecule contains many effective atoms. 

Examples of simple antistatic agent mixtures are alkanolamines mixed with fatty acids, alcohols, or amides and eventually with metallic oxides or hydroxides. An example of a combination antistatic agent is the N-methyl-iV-stearyl-
