    摘要： Polymer blends containa) from 20 to 70% by weight of a propylene copolymer which in turn consists of from 20 to 65% by weight of a propylene homopolymer and 30 to 85% by weight of a random propylene copolymer containing polymerized C.sub.2 -C.sub.10 -alk-1-enes andb) from 30 to 80% by weight of a polyethylene having a density of from 0.94 to 0.98 g/cm.sup.3 and a melt flow index of less than 15 g/10 min at 190.degree. C. under a weight of 2.16 kg.The novel polymer blends possess, inter alia, high rigidity, high impact strength and little tendency to undergo white fracture and are particularly suitable for the production of films and moldings.

    摘要： 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.
