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.

Abstract: A process is disclosed for preparing ethylene polymers with a molecular weight Mw (weight average) lower than 20,000 g/mole at temperatures in a range from 200 to 280 DEG C and pressures in a range from 1000 to 3500 bars in the presence of a catalyst system. The catalyst system used contains: (A) a non-bridged substituted or unsubstituted biscyclopentadienyl complex; (B) a metal compound of general formula (I) M (R )r (R )s (R )t, in which M is an alkaline, an alkaline earth metal or a metal of the third main group of the periodic table; R is hydrogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl or arylalkyl with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; R and R independently represent hydrogen, halogen, C1-C10-alkyl, C6-C15-aryl, alkylaryl, arylalkyl or alkoxy with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; r is an integer from 1 to 3; and s and t are integers from 0 to 2, the sum r+s+t corresponding to the valency of M ; and (C) a metallocene ion-forming compound selected in a group which consists of strong, neutral Lewis acids, ionic compounds with lewis acid cations and ionic compounds with Brönsted acids as cations. Components (A), (B) and (C) are mixed together and after at the latest 5 minutes are dosed in the reactor.
