| titleOfInvention | Process for preparing polyolefins |
| abstract | ABSTRACT OF THE DISCLOSURE A process is provided herein for preparing polyolefins by polymerizing or copolymerizing olefins using as the catalyst a titanium compound-containing solid component and an organometal compound. The solid component comprises a substance obtained by copulverizing (1) mag-nesium halide and/or manganese halide, (2) an organic halide compound, (3) a chain or cyclic silicons compound with recurring structure unit represented by the general formula wherein R' and R" res-pectively represent hydrogen, alkyl, aryl, alkoxy or hydroxyl group and (4) tetravalent and/or trivalent titanium compounds(s). The magnesium halide and/or manganese halide to the organic halide compound is in the range of from 1:0.5 to 1:0.01; wherein the weight ratio of the magnesium halide and/or manganese halide to the silicone compound is in the range of from 1:0.5 to 1:0.004; and wherein the solid component contains titanium in an amount ranging from 0.5 to 10% by weight. The polymers so produced are produced in high yield and have high bulk density. In addition, the catalyst removing step may be omitted. The polymers have a wide distribution of molecular weight being obtained as powders of high bulk density. |
