Abstract
In polyamides containing the reaction product of (1) a propylene oxide-ethylene oxide block copolymer based on ethylene diamine and (2) a dicarboxylic acid ester in an amount sufficient to provide improved antistatic characteristics to the polyamide, the tensile strength loss on exposure to heat is reduced by adding a thermal stabilizing amount of a phosphine oxide.
