<p>A pigment dispersant for aromatic polymers which is excellent in the ability to dispers pigments in aromatic polymers, can give pigmented aromatic polymer compositions excellent in transparency and color stability, and can be prepared without any grafting step at a low cost. The dispersant consists of an ethylene/vinyl aromatic copolymer wax comprising 99 to 10 wt. % of structural units derived from ethylene and 1 to 90 wt. % of structural units derived from an aromatic vinyl compound and having an intrinsic viscosity of 0.04 to 0.6 dl/g.</p> |
