Abstract:
    The invention relates to Polypropylene homo- or copolymer waxes are used as components for the production of toners. The waxes have fewer than 10% unsaturated chain ends and a melt viscosity of 10-100000 mPa.s at 170 DEG C; and are produced by polymerization using metallocene compounds in the presence of hydrogen. These waxes have very satisfactory thermal stability and do not cause the discoloration and crosslinking of a melt of the waxes.
