Abstract
PURPOSE: To prepare a stabilized polyolefin, by adding an epoxide to a polyolefin slurry having specific granule properties, by removing part of the liguid from the inactivated slurry, and by evaporating the rest of the liquid.
CONSTITUTION: A polyolefin having a bulk density ≥0.4g/cc and a porosity ≥0.2g/ cc, which is obtained by polymerizing an α-olefin in the presence of a catalyst having a catalylic efficiency ≥5,000 consisting of a transition metal halide and an orgonoaluminum compound, is changed into a slurry with a concentration of 5W55wt% and a sedimentation concentration ≥50wt%. A 2W8C epoxide in an amount of 15 times the molar amount of the catalyst component in the slury is, added to the slurry, and the remaining catalyst is inactivated by heating at a temperature ranging from ordinany one to the decomposition temperature of the polymer or below to separate part of the liquid phase. Crude polylefin with the liquid content <40wt% is thus separated, and the liquid component contained in the crude polyolefin is evaporated.
