发明名称 Stabilizer combination for the rotomolding process
摘要 A description is given of a process for the production of polyolefin hollow articles, which comprises charging the polyolefin with a stabilizer combination, comprising (A) at least one compound from the group of the organic phosphites or phosphonites, and (B) at least one compound from the group of the 3-arylbenzofuranones, filling this mixture into a mold, heating this mold in an oven to above 280 DEG C., such that the stabilised polyolefin fuses, rotating the mold around at least 2 axes, the plastic spreading to the walls, and cooling the mold while still rotating, opening it and taking the resultant hollow article out.
