Abstract
In polyamide compositions containing the reaction product of (1) a block copolymer of propylene oxide, ethylene oxide, and an alkylene diamine and (2) a dicarboxylic acid ester in an amount sufficient to provide improved antistatic characteristics to the polyamide, the apparent dyeability can be increased by including in said polyamide composition a sufficient amount of at least one zinc sulfinate of the formula: EQU Zn(R"SO.sub.2).sub.2 wherein R" is an alkyl group containing from 4 to 20 carbon atoms.
