Реферат: A process for preparing a polyethylene composition comprising bimodal or multimodal polyethylene in an extruder device comprising mixing a bimodal or multimodal polyethylene having a density from 0.940 g/cm 3 to 0.968 g/cm 3 in form of a polyethylene powder and one or more additives in a mixing device at a temperature from 10°C to 100°C without melting the polyethylene powder; melting and homogenizing the mixture within the extruder device to form a molten polyethylene composition; and pelletizing the molten polyethylene composition, wherein a liquid comprising an organic peroxide is added in an amount from 20 ppm to 200 ppm of organic peroxide with respect to the polyethylene powder, and the liquid is added to the polyethylene powder at a position where mixing occurs and where the polyethylene powder has a temperature of from 10°C to 100°C.
