Abstract
A maleated saturated hydrocarbon wax having a number-average molecular weight of 500 through 6000, a content of a maleic anhydride unit of 14 through 40% by weight and a melt viscosity of 10.sup.2 through 10.sup.6 centipoises at 140.degree. C. is disclosed. This maleated wax is self-emulsifiable and the emulsion thereof can be stored for a long period of time, even in a very dilute emulsion. This maleated wax is produced from the reaction of a saturated hydrocarbon wax with the specified amount of maleic anhydride, in the presence of an organic peroxide, at the specified temperature by adding the maleic anhydride and the organic peroxide to the molten saturated hydrocarbon wax at the specified rates.
