WHEREIN R AND R'' ARE INDEPENDENTLY AT EACH OCCURRENCE HYDROGEN, METHYL OR ETHYL AND R, S, AND T ARE INTEGERS FROM 31 TO ABOUT 200. HOWEVER, WITH INCORPORATION OF THIS ANTISTATIC ADDITIVE IN THE POLYAMIDE, SERIOUS PROBLEMS HAVE BEEN ENCOUNTERED IN MELT-SPINNING DUE TO THE FREQUENT OCCURRENCE OF "NUBS OR ENLARGED PLACES IN THE EXTRUDED POLAMIDE FILAMENT. IT HAS NOW BEEN FOUND THAT THE OCCURRENCE OF SAID NUBS IN THE ANTISTATIC POLYAMIDEFIBER CAN BE GREATLY REDUCED BY DISPERSING IN THE POLYMER AT LEAST 0.5% BY WEIGHT, BASED ON THE WEIGHT OF THE ANTISTATIC AGENT, OF A PHENOL COMPOUND REPRESENTED BY THE FORMULA: 2-R2,4-R1,6-R3-PHENOL WHERE R1 IS HYDROGEN OR AN ALKYL RADICAL CONTAINING 1 TO 5 CARBON ATOMS, R2 IS AN ALKYL RADICAL CONTAINING 12 TO 18 CARBON ATOMS, AND R3 IS AN ALKYL RADICAL CONTAINING 12 TO 18 CARBON ATOMS, AND AT LEAST 0.5% BY WEIGHT, BASED ON THE WEIGHT OF THE ANTISTATIC ADDITIVE, OF A SULFUR COMPOUND OF THE FORMULA. R4-OOC-CH2-CH2-S-CH2-CH2-COO-R5 WHERE R4 IS AN ALKYL CONTAINING 8 TO 18 CARBON ATOMS AND R5 IS AN ALKYL RADICAL CONTAINING 8 TO 18 CARBON ATOMS.

IT HAS BEEN SUGGESTED THAT THE UTILITY OF SYNTHETIC FIBERS OF POLYAMIDE COULD BE INCREASED BY DISPERSING IN THE POLYAMIDE ABOUT 1 PERCENT TO ABOUT 10 PERCENT OF A COMPOUND REPRESENTED BY THE FORMULA:
