Abstract
The invention relates to polyamide compositions of high-molecular weight, linear aliphatic polyamides with reduced surface resistance which are produced by solvent-free condensation of salts of aliphatic diamines and aliphatic dicarboxylic acids and/or of lactams and in which polyester amides which have been obtained by condensation of dicarboxylic acids or their derivatives, diols and primary-secondary aliphatic diamines are homogeneously distributed.
