    摘要： The present invention relates to diamide-polyolefin wax mixture comprising one or more diamides (A) and one or more polyolefin waxes (B), where the diamide or diamides (A) possess a structure of the formula X1—CO—NH—Y—NH—CO—X2, in which X1 and X2 are identical or different and are linear or branched, saturated or unsaturated, optionally substituted hydrocarbon radicals having 3 to 29 carbon atoms, and Y is a divalent organic radical which is selected from the group consisting of aliphatic radicals having 2 to 26 carbon atoms, aromatic radicals having 6 to 24 carbon atoms or araliphatic radicals having 7 to 24 carbon atoms, and Y optionally comprises secondary or tertiary amino groups, and the polyolefin wax or waxes (B) carry one or more carboxyl groups and have an acid number of 3 to 50, and are homopolymers or copolymers of at least one ethylenically unsaturated olefin monomer, where the diamide or diamides (A), based on the total weight of the diamide-polyolefin wax mixture, are present in an amount of 20 wt % to less than 40 wt %, the polyolefin wax or waxes (B), based on the total weight of the diamide-polyolefin wax mixture, are present in an amount of above 60 wt % up to 80 wt %, characterized in that the diamide-polyolefin wax mixture at 25° C. is a particulate solid of defined particle size distribution, and the particles comprise both the diamide (A) and the polyolefin wax (B). The invention further relates to the preparation of the aforesaid diamide-polyolefin wax mixture, to the use thereof in liquid compositions, especially as a rheology control agent, to compositions additized accordingly, and to rheology control agents which comprise the diamide-polyolefin wax mixtures.
