This invention relates to hydantoin polyamide-poly(oxyethylene) block copolymers which have good thermal stability and an increased hydrophilicity of the polyamide blocks, and which can be used as an additive to polyamides, resulting in improved antistatic properties of the polyamides. The formula for a typical copolymer is: ##STR1## IN WHICH X IS 2 TO 5, Y IS ABOUT 23, AND Z IS 2 TO 3.
