Abstract
Several quaternary ammonium salts were synthesized from N, N-dimethyl-amino ethyl polyoxyethylene alkylether and ethylchloro-acetate, α-chloroacetamide, p-toluene sulfochloride. Metal complexes were also prepared from two moles of N, N-dimethylamino ethyl polyoxyethylene alkylether with one mole of calcium chloride, or nickel chloride.
The effect of these compounds as antistatic agents for PVC was evaluated by measuring the frictional charge generation, induced charge decay, surface resistance and thermal stability.
The antistatic effect of ammonium salts was better than that of metal complexes, but thermal stability was less. Metal complexes having stearyl group were more effective than those having lauryl group, but such difference was not observed as to alkyl group in ammonium salts.
The moles of added ethylene oxide showed little difference, in 5-20 mole range.
