    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a transition metal catalyst with carrier easily practicable on an industrial scale without causing film formation on the inner wall of a reaction vessel so as to uniformly bearing the catalyst on a carrier material. SOLUTION: This method for producing a transition metal catalyst with carrier comprises gradually adding a solution of a transition metal complex based on group VIIIB, IB or IIB element (optionally its mixture with a cocatalyst) to a particulate organic or inorganic carrier material in such a manner that the volume of the solution to be used is double or less the porosity of the carrier material to effect entirely renewing the surface of the carrier material.

    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.
