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 in the solid component, as the carboxylic acid ester, a diester of a carboxylic acid of the formula Ia or Ib in which R , R , R and R are identical or different and are hydrogen, C1-C15-alkyl, C7-C15-alkylaryl or 5- to 7-membered cycloalkyl, which may itself carry C1- to C10-alkyl groups. 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: Copolymers of propylene (prop) and hex-1-ene (hex) are claimed (I). (I) are obtd. by copolymerisation at 10-50 br and 50-100 deg. C for 1-5 hrs. (mean residence time) in the presence of a Ziegler-Natta catalyst system comprising a solid, Ti-contg. component (A), an Al component (B) and an electron donor (C). The temp. at the given pressure is high enough to prevent condensn. of the monomer mixt. in the gas space and the ratio of partial pressures (prop):(hex) = (1:1)-(120:1). USE/ADVANTAGE - Enables the prodn. of propylene/hex-1-ene copolymers (I), which are useful for the mfr. of film (e.g, for use in the food industry), tubes, coatings, fibres hollow mouldings, injection moulded prods. and moulded prods. for use in cars. (I) are statistical copolymers with mol. wt of 10,000-500,000 and MFI 0.1-100 (pref. 0.2-50) g/10 mins., esp. contg. 0.1-10 wt. % hexene and with a low heptane-solubles content. The claims also include films and moulded prods. made from (I).
