Abstract
Abstract 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 DEG C and from 0.02 to 35 weight percent of a phosphonium salt of a phosphonate, phosphinate, or sulfonate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
125 words
An antistatic composition having a log R s of less than 8 and consisting essentially of an N-alkylpolycarbonamide having a Tg (NMR) of less than 25° C and from 0.02 to 35 weight percent based on the weight of the composition of a phosphonium salt of the formula [R.sub.1 R.sub.2 R.sub.3 R.sub.4 P.sup.+].sub.n X.sup.n.sup.- where R 1 R 2 R 3 and R 4 each represents a monovalent hydrocarbon group of from 1-18 carbon atoms; X n - is an organic anion selected from the group of ##STR2##and R(SO 3 - ) m wherein Ar is an aromatic hydrocarbon radical; R is an aliphatic or an aromatic hydrocarbon radical; m is 1 or 2; and n, the valence of the anion, is 1 or 2.
Claim 2
Dependent Claim
125 words
An antistatic composition having a log R s of less than 8 and consisting essentially of an N-alkylpolycarbonamide having a Tg (NMR) of less than 25° C and from 0.02 to 35 weight percent based on the weight of the composition of a phosphonium salt of the formula [R.sub.1 R.sub.2 R.sub.3 R.sub.4 P.sup.+].sub.n X.sup.n.sup.- where R 1 R 2 R 3 and R 4 each represents a monovalent hydrocarbon group of from 1-18 carbon atoms; X n - is an organic anion selected from the group of ##STR2##and R(SO 3 - ) m wherein Ar is an aromatic hydrocarbon radical; R is an aliphatic or an aromatic hydrocarbon radical; m is 1 or 2; and n, the valence of the anion, is 1 or 2.
