    Abstract: Propylene/ethylene block copolymers are prepared by a process in which, in an agitated bed comprising small polymer particles, first (I) propylene is homopolymerized from the gas phase, in a first polymerization zone, by feeding in a Ziegler-Natta catalyst comprising (1) a titanium(III) component and (2) a dialkyl-aluminum chloride component, with or without (3) a further catalyst component, and then (II) the product obtained in the first polymerization zone is fed into a second polymerization zone, where a mixture of propylene and ethylene is polymerized with the propylene homopolymer present in this product. In this process, the Ziegler-Natta catalyst employed contains a titanium(III) component (1) which is prepared by subjecting (1.1) a titanium-containing compound (a) of the formula TiCl3. nAlCl3 and (1.2) an electron donor (b), consisting of (b1) an ester of a particular class or (b2) a phosphorus-containing compound of a particular class, to a special milling procedure, the particular features of which are special metering and temperature conditions, suspending the resulting intermediate in a mixture of a liquid hydrocarbon (c) and an oxygen-containing compound (d), comprising (d1) an ether of a certain class and/or (d2) an ester of a certain class, and then heating the suspension obtained. The solid remaining in suspension is the titanium(III) component (1) which is to be employed for the polymerization. The polymer obtained has improved morphological properties.

    Abstract: A random copolymer (I) of propylene with other 2-10 C 1-alkenes comprises 0.7-1.4 wt.% ethylene comonomer or 0.7-3.0 wt.% 4-10 C 1-alkene. (I) has a solubility in cold xylene of 1.0-2.5 wt.% or 0.75-2.0 wt.% when the comonomer is ethylene or a 4-10C 1-alkene respectively. Independent claims are included for: (i) a process for the preparation of (I) by the gas phase polymerisation of propylene and a 2-10 C 1-alkene at 50-100 degrees C and 15-40 bar in the presence of a Ziegler-Natta catalyst containing: (A) a titanium containing solid component containing at least a halogen containing magnesium compound and an electron donor; (B) an aluminum compound; and (C) at least a further electron donor compound. The ratio of partial pressure of propylene to comonomer is 400:1-15:1 and the molar ratio of (B) to (C) is 20:1-2:1; and (ii) film, fiber or molded articles containing (I).
