Claims
- 1. A conductive N-alkyl polyamide having a glass transition temperature measured by nuclear magnetic resonance peak ratio of less than 25.degree. C., a log R.sub.s of less than 10 and having units containing phosphonium sulfonate groups of the formula ##STR5## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent monovalent hydrocarbon groups with the proviso that R.sub.1 and R.sub.2 may jointly represent an alkylene group, Y is a hydrocarbon group of up to 24 carbon atoms in which any unsaturation is aromatic and which may be interrupted by oxygen, sulfonamide or sulfonyl groups, Z is selected from the group consisting of ##STR6## --O-- and ##STR7## wherein R is hydrogen or an alkyl group of 1-18 carbon atoms and n and m are 1 or 2, said groups being present in an amount of from 0.01 mol % to about 50 mol % based on the total mols of dicarboxylic acid units and/or aminocarboxylic acid units in the polymer chain.
- 2. The polymer of claim 1 wherein the unit containing the phosphonium sulfonate group is a phosphonium 3,5-dicarbonylbenzene sulfonate unit.
- 3. The polymer of claim 1 having a log R.sub.s of less than 8.
