64.2 g neopentyl glycol (0.617 mole), 246.9 g montanic acid (0.617 mole) and 0.4 g tin powder were heated to 210° C. as in Example 1 with application of a gentle vacuum. The vacuum was increased to 150 mbar over a period of 5 h. The product had an acid number of approximately 2. A brown-yellow hard wax having a dropping point of 72° C. was obtained after cooling to 100° C., bleaching and filtering.
