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

Abstract: Catalyst systems of the Ziegler-Natta catalyst type, containing, as active constituents, a) a titanium-containing solid component which contains titanium, magnesium, halogen and a carboxylic acid ester, and, as cocatalyst, b) an aluminium compound and c) optionally further electron-donor compounds, characterised in that they contain, as the carboxylic acid ester in the solid component a), an ester of a benzophenone-2-carboxylic acid of the formula I in which R is a hydrogen atom, a C1-C15-alkyl group or a halogen atom. These catalyst systems are particularly suitable for the preparation of polypropylene and copolymers of propylene with minor amounts of other alpha , beta -unsaturated olefinic compounds having 2 to 12 carbon atoms.

Abstract: A novel Phillips catalyst for the homopolymerisation of ethylene and the copolymerisation of ethylene with alpha -olefins contains, as catalytically active components, a specific aluminium phosphate-supported chromium catalyst and cocatalysts of the general formulae I to IV MR M R2 M R 3-nXn MM RR@ (I) (II) (III) (IV> in which the index and variables have the following meanings: M is lithium, sodium or potassium, M is magnesium or zinc, M is boron or aluminium, R is C1- to C10-alkyl or C6- to C20-aryl, R is R or C1- to C10-alkoxy or C6- to C20-aryloxy, X is chlorine, bromine or iodine, N is 0, 1 or 2. The aluminium phosphate-supported chromium catalyst is obtainable by applying chromium compounds to a finely divided aluminium phosphate having a P:Al molar ratio of close or equal to 1 and a pore volume of > 1 cm /g, and activating the resulting intermediate at elevated temperatures in an oxidising atmosphere. The novel Phillips catalyst has an extremely long mean service life, and its productivity can be further increased by adding hydrogen.
