Abstract: Granules are concentrated in a side stream of the water used during granulation (for cooling and cutter lubrication). This side stream forms the conveying medium for the granules. Preferred features: The side stream of granulation water contains 15-35 wt%, preferably 15-25 wt% of granules. Separation between granulator (C) and storage location exceeds 200 m, preferably exceeding 500 m. Drying of granules takes place in the immediate vicinity of further treatment and/or storage. Side stream temperature after leaving the separator (D) is raised, especially through 5-40 deg K. Vertical relationships between: granulator, side stream handling plant (G), and if appropriate, the drying unit (H), facilitate granule conveying to further processing and/or storage.

Abstract: Propylene/ethylene block copolymers are prepared by a continuous process in which, in each case in an agitated fixed bed of finely divided polymer from the gas phase, first (I) in a first polymerization zone, propylene is homopolymerized by feeding in a Ziegler-Natta catalyst system consisting of (1) a titanium component which contains titanium, magnesium, chlorine and a phthalic acid derivative, (2) an aluminumalkyl component and (3) a silane component, and (II) in a second polymerization zone, a mixture of propylene and ethylene is polymerized with the propylene homopolymer present in the reaction mixture obtained in the first polymerization zone by feeding in the said reaction mixture. In the process, (A) a titanium component (1) is used which is obtained by a method in which (1.1) first, (1.1.1) in a liquid hydrocarbon, (1.1.2) a finely divided magnesium halide, (1.1.3) an alkanol, (1.1.4) a certain phthalic acid derivative and (1.1.5) titanium tetrachloride are reacted with one another under certain conditions, (1.2) the solid intermediate obtained from (1.1) is extracted with titanium tetrachloride or a liquid alkylbenzene until the remaining solid substance has become substantially richer in magnesium, and (1.3) finally, the solid substance remaining in (1.2) is washed with an alkane in a certain manner, (B) a specific silane is used as (3), and (C) specifically selected polymerization parameters are employed, with relationships between the first and second polymerization zones.
