Abstract: Method for polymerizing an alpha-olefin or copolymerizing an alpha-olefin with another olefin in the presence of a catalyst obtained by subjecting to a first reaction, a halogenide of trivalent metal together with at least one kind of compound selected from the group consisting of halogenide hydrates, sulfide hydrates, sulfate hydrates, hydroxides and hydroxide hydrates of metals belonging to the I-VIII groups of the periodical table so as to form active groups on the surface, then reacting the resultant first reaction product with a transition metal compound and further combining the resultant second reaction product thus obtained with an organoaluminum compound. The above-mentioned second reaction is preferably carried out in the presence of an aromatic solvent. As the above-mentioned compounds of metals of the I-VIII groups, the hydroxides of the II group, particularly magnesium hydroxide and calcium hydroxide, are preferably selected. In this case, the above-mentioned first and second reactions are both carried out at a temperature of 110*C or below. The above-mentioned polymerization or copolymerization in the presence of the above-mentioned catalyst is preferably carried out in the presence of a titanium alkoxide and hydrogen in an amount more than 10% and less than 80% by volume based upon the total amount of ethylene and hydrogen.

Abstract: Titanium trichloride-containing compositions for use as catalyst component in stereoregular olefin polymerization are prepared by gradual addition of a solution of titanium tetrachloride to a solution of trialkyl aluminum in certain low-boiling inert diluents. The mixture is prepared and held at a temperature below about -90* C until addition is complete, is thereafter gradually warmed up at least to ambient temperature but not above 80* C and held until reduction of TiCl4 to TiCl5 is complete, and is then heated to an elevated temperature at which the TiCl3 is converted to the violet form. Refinements of this procedure include control of mixing and heating rates and post-treatment of the reaction product to produce catalyst components having various desired properties. According to one mode of the invention, titanium trichloridecontaining compositions can be obtained in particles which are larger and/or more clear and glassy and/or have a smoother surface than can be obtained when the mixing of titanium tetrachloride with aluminum trialkyl is carried out at conditions outside those specified. Used with dialkyl aluminum chloride in the polymerization of propylene, such compositions can produce excellent stereoregular polypropylene in the form of polymer particles of high bulk density which are substantially free of fines and hence non-dusting and exhibiting good powder flow. According to a second mode, titanium trichloride-containing compositions can be obtained in particles which, while still relatively dense, have a porous surface. Used with dialkyl aluminum chloride, these compositions are especially suitable for use in staged propylene polymerization followed by ethylenepropylene copolymerization to produce impact-improved polypropylene compositions.
