A process for the preparation of a modified polyolefin wax having improved hardness and gloss, which comprises reacting a waxy polyolefin with maleic anhydride to produce a maleinised polyolefin wax, reacting at 100 DEG - 180 DEG C the thus-produced maleinised wax with water in an amount of 2 - 80 parts by weight per 100 parts by weight of the maleic anhydride reacted with the waxy polyolefin and, if desired, distilling off from the reaction system an excess of the water remaining therein after the end of the hydrolytic reaction, at a temperature of 100 DEG - 180 DEG C under atmospheric or a reduced pressure.
