    Abstract: PROBLEM TO BE SOLVED: To provide Ziegler/Natta catalyst composition capable of providing a high productivity and stereospecificity, producible in a short time and capable of reducing the amount a titanium- or a chlorine-containing starting material. SOLUTION: This Ziegler/Natta catalyst composition comprises (a) a titanium- containing solid component, (b) an aluminum compound and, as necessary, (c) an electron donative compound. The component (a) is produced by mixing an inorganic compound as a carrier with a solution of a magnesium compound without containing chlorine in an inert solvent, then reacting the resultant mixture with a 1-8C alkanol in an excessive amount of >=1.3 times based on the magnesium compound at -20 to +80 deg.C under stirring, subsequently mixing the prepared product with a tri- or a tetravalent titanium compound and a carboxylic acid ester as an electron donor without carrying out the purification and extraction thereof, then separating a solid material by filtration, extracting the resultant solid with a solution containing >=5wt.% titanium tetrachloride in an inert solvent and further washing the solid material with a liquid alkane.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition comprising a specific titanium- containing solid component, a cocatalyst and an electron-donating compound and enabling the production of a polymer having a high bulk density and reduced in xylene and heptane-soluble contents. SOLUTION: This Ziegler/Natta type catalyst composition comprises (A) a Ti-containing solid component comprising a Ti compound, a Mg compound, a halogen, an inorganic oxide and a carboxylate ester as an electron-donating compound, (B) an aluminum compound as a cocatalyst, and selectively (C) one or more other electron-donating compounds. The inorganic oxide in the component A has a pH of 1-6, an average particle diameter of 5-200μm, an average primary particle diameter of 1-20μm, pore spaces and grooves of 0.1-20μm and the whole particle volume marcroshare of 5-30%. The catalyst can give polymers good in mechanical characteristics, and the polymers are suitable for producing shaped products such as films and fibers.
