摘要： Conductive compositions useful in imparting antistatic properties in filaments and other articles are provided, which comprise N-alkyl polycarbonamides, polyesters or polyetheresters having a Tg (NMR) less than 25.degree. C and from 0.02 to 35 weight percent of a phosphonium salt of a phosphonate, phosphinate, or sulfonate.
