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 dihydrocarbyl dithiophosphinate.
