Abstract: Propylene-ethylene copolymers (I) are claimed; (I) are obtd. by 2-stage, gas-phase polymerisation in an agitated solid bed, with a Ziegler-Natta catalyst system contg. Ti-contg. solid components and Al cpd. as co-catalyst; process comprises (i) polymerisation of propylene at 20-40 bar, 60-90 deg.C and a residence time of 1-5 hrs., to give 0.05-2 kg PP/mmol Al cpd., then (ii) polymerisation of a mixt. of propylene and ethylene (ratio of partial pressures P:E = (0.5:1):(5:11) at 5-30 bar (at least 7 bar below the pressure in stage (i), 30-100 deg.C and a residence time of 1-5 hrs.; (a) the wt. ratio between the monomers reacted in stages (i) and (ii) is (2.5:1)-(20:1), or (b) (ii) polymerisation is carried out in the presence of a 1-8C alkanol (II), in which case the above wt. ratio (1:1)-(20:1). The above process is claimed as such. Pref., (II) is a 1-4C alkanol. USE/ADVANTAGE - Useful for the prodn. of film, tubing, coatings, fibre, hollow mouldings, injection moulded articles and moulded pts. for vehicles. Film and moulded prods. produced from (I) are claimed as such. Provides EP copolymers (I) with good rigidity, improved free flowing properties, a satisfactory level of notch impact strength, high bulk density and a low content of catalyst residues.

Abstract: >A process for the preparation of propylene-ethylene copolymers by two-step polymerisation from the gas phase in an agitated fixed bed by means of a Ziegler-Natta catalyst system which, in addition to a titanium-containing solids component, also contains, as cocatalyst, an aluminium compound, where the Ziegler-Natta catalyst system used is one which, after the reaction of the titanium-containing solids component with the cocatalyst, is deactivated by reaction with carbon dioxide.
