Abstract
Alkali or alkaline earth metal salts of the reaction product of certain polyalkylene glycols of the formula ##EQU1## wherein N = 0 TO 100 (m+p) = 10 to 500 ##EQU2## WITH A SULTONE. These products are superior and long lasting antistatic agents for use in connection with polyamide synthetic fibers. Polyamides compositions having antistatic properties as well as methods for manufacture of such compositions are also disclosed.
