Abstract

A process for the preparation of a polyolefin wax by polymerization or co-polymerization of olefines or diolefins at a temperature of -40.degree. to 100.degree. C. at a pressure of 0.5 to 120 bar, in suspension and in the presence of a metallocene catalyst and a co-catalyst, thereby producing wax products in solid form which may be easily separated from the suspending agent and the catalyst need not be separated off.
