Abstract
Dry powdered wire drawing lubricant compositions are disclosed for the most severe drafting conditions in which mixtures of polymers of Poly (3,5-dithio-1,2,4-thiadiazole) and Poly (2,5-dithio-1,3,4-thiadiazole) act synergistically with molybdenum disulfide as extreme pressure additives. The polymers of Poly(3,5-dithio-1,2,4-thiadiazole) and Poly(2,5-dithio-1,3,4-thiadiazole) can also be used as the sole extreme pressure additive in the wire drawing lubricants.
