    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: Propylene-ethylene copolymers obtainable by two-step polymerisation from the gas phase in an agitated fixed bed by means of a Ziegler-Natta catalyst system containing an aluminium compound as cocatalyst in addition to a titanium-containing solid component, in which, in a first polymerisation step, propylene is polymerised at a pressure of from 20 to 40 bar, a temperature of from 60 to 90 DEG C and a mean residence time of the reaction mixture of from 1 to 5 hours, giving from 0.05 to 2 kg of polypropylene per mmol of the aluminium compound, and subsequently, in a second polymerisation step, a mixture of propylene and ethylene is polymerised onto the polymer discharged from the first polymerisation step, at a pressure of from 5 to 30 bar, this pressure being at least 7 bar below the pressure in the first polymerisation step, a temperature of from 30 to 100 DEG C and a mean residence time of the reaction mixture of from 1 to 5 hours, the ratio between the partial pressures of propylene and ethylene being set in the range from 0.5 : 1 to 5 : 1, and a) the weight ratio between the monomers reacted in the first and second polymerisation steps is set so that it is in the range from 2.5 : 1 to 20 : 1, or b) the polymerisation in the second polymerisation step is carried out in the presence of a C1-C8 alkanol, the weight ratio between the monomers reacted in the first and the second polymerisation steps being from 1 : 1 to 20 : 1. s
