| titleOfInvention | Process for producing olefin polymer |
| abstract | ABSTRACT OF THE DISCLOSURE A process for producing an olefin polymer which com-prises homopolymerizing or copolymerizing an olefin in the pres-ence of a catalyst system composed of an organoaluminum compound and a hydrocarbyloxy group-containing solid catalyst component which is prepared by reducing a titanium compound represented by the general formula Ti(OR1)nX4-n, wherein R1 is a C1-C20 hydro-carbon radical, X is halogen, and n is a number defined as 0 < n ? 4, with an organoaluminum compound represented by the general formula A?R2mY3-m, wherein R2 is a C1-C20 hydrocarbon radical, Y is halogen, and m is a number defined as 1 ? m ? 3, subjecting the reduction product which is a hydrocarbyloxy group-containing solid insoluble in hydrocarbon solvents and in which the hydro-carbyloxy group content is 0.3 to 2.5 moles per mole of titanium atoms, to a preliminary ethylene polymerization treatment, and treating the resultant solid in a state of slurry in a hydrocar-bon solvent with an ether compound and titanium tetrachloride at a temperature of 30° to 100°C. |
