Process for preparing polyolefin resin extended pigments

摘要: A process is disclosed for preparing resin extended pigments containing from 10% to 75% and preferably 25% 50% by weight, based on the amount of pigment present. The crude are premilled dry, such as in a ball mill, manner equivalent that used prepare small particle size highly aggregated pigment. Following premilling milled an organic liquid capable ripening particles pigmentary or simply improving their crystallinity which at 30° C., can dissolve no more than 5 g/l 2 resin.
