Abstract:
1. A process for production of an inorganic filler-containing polyolefin resin composition, in which the process carries out a continuous series of steps train an olefin polymerizatzon step up to a kneadinglpelletizing step where the polyolefin resin obtained by the polymerization step is kneaded and pelletized with an inorganic filler and one or more additives, the process being carried out in a continuous series of steps such that the steps are carried out an a connected process line and the polyolefin resin does not exit the process line before having been pelletized to produce the inorganic filler-containing polyolefin resin composition and that the polyolefin resin, the inorganic filler and the one or more additives are premixed between the polymerization step and the kneading/pelletizing step.
