An oxidized polyolefin wax having a molecular weight Mw in the range from 1000 to 40,000 g/mol, obtainable by oxidizing polyolefins prepared by catalysis using a single-site catalyst based on a complex of a transition metal from groups 5 to 8 of the Periodic Table of the Elements containing not more than one cyclopentadienyl system per metal atom.
A process for preparing an oxidized polyolefin wax by oxidizing polyolefins having a molecular weight Mw in the range from 1000 to 40,000 g/mol with oxygen agents at a temperature in the range from 140 to 350° C., which comprises using polyolefins obtainable by catalysis using a single site catalyst based on a complex of a transition metal from groups 5 to 8 of the Periodic Table of the Elements containing not more than one cyclopentadienyl system per metal atom.
