Abstract: PROBLEM TO BE SOLVED: To obtain an oxidized polyolefin wax having a narrow acid value distribution continuously in a high time and space yield by continuously reacting a polyolefin wax with oxygen or an oxygen-contg. gas in a tubular reactor at specified temp. and pressure (provided the reaction of a polyolefin obtd. with a metallocene catalyst is excluded). SOLUTION: A polyolefin wax is reacted at 140-200 deg.C under 5-200 bar. The use of air is pref. for oxidizing a polyolefin. Pref., at least two zones with temps. different from each other are established in the heating jacket of the tubular reactor, and the temp. of the preceding zone is set 5-20 deg.C higher than that of the following zone. The average dwell time is usually 0.5-20 hr. Pref., the ratio of flow rate of the oxidizing gas to the wax passing through the reactor is set at 30-500. Thus is obtd. an oxidized polyolefin wax having an acid value of 1-150.

Abstract: A process for the production of oxidised polyolefin wax (I) comprises the continuous reaction of polyolefin wax (II) with oxygen or oxygen-containing gas at 140-200 degrees C and 5-200 bar in a tubular reactor, excluding polyolefins obtained by metallocene catalysis. Also claimed is oxidised polyolefin wax (I) obtained by this process, preferably with an acid number of 10-50.
