    摘要: Polypropylene wax having a) a dropping or softening point determined by the ring/ball method of greater than 155° C., b) heats of fusion greater than 80 J/g and c) a DSC melting point of >155° C. The waxes of the invention are prepared by reaction of propylene with metallocene compounds at temperatures in the range from 40 to 140° C. and an olefin partial pressure in the range from 1 to 50 bar in the presence of a cocatalyst. They have a content of unsaturated chain ends of less than 10%. They can, for example, be modified by means of a free-radical grafting reaction with polar monomers and are, for example, suitable in unmodified form as dispersants for pigments, as additive in printing inks and surface coatings or toners or in modified form for producing aqueous dispersions or as bonding agents and compatibilizers in plastic compounds.
