| 摘要 |
The invention relates to pigment concentrates for coloring thermoplastics, comprising—at least one color pigment—at least one copolymer wax, produced by converting long-chain olefin hydrocarbon in the chain length range of≧12 C-atoms having unsaturated polycarboxylic acids or anhydrides thereof in the presence of at least one radical starter and comprising a) 40-60 mol-% units derived fromα-olefins of the chain length C12-C60, preferably C24-C60, particularly preferably C28-C60 and b) 60-40 mol-% units that derive from unsaturated polycarbolxylic acids or anhydrides thereof, and at least one thermoplastic polyolefin as applicable. |
