Abstract
PURPOSE: To prepare a highly stereoregular polyolefin, by (co)polymerizing an olefin or its mixture in the presence of a specific highly active catalyst on a high- performance carrier.
CONSTITUTION: An olefin or its mixture is (co)polymerized in the presence of a catalyst consisting of (A) a solid component, obtained by simultaneous pulverization of (a) 1 mole of MgO, (b) 0.001W10 moles of an aluminum halide, (c) 0.001W5 moles of a hydroxyl compound of the formula ROH (R is 1W20C organic residue), (d) 0.5W10 wt.% based on Ti of a Ti halide and/or its adduct with an aromatic carboxylate at 0W50°C for 0.5W50hr, and (B) an organic compound of metals of Groups IWIV in the periodic table and/or its adduct with an aromatic carboxylate, and (C) an aromatic carboxylate at 20W300°C and normal pressure to 70 kg/cm2.G.
