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 process for the preparation of propylene-ethylene copolymers in an agitated fixed bed in which propylene is polymerised from the gas phase, initially in a first polymerisation zone at a pressure of from 20 to 40 bar and at a temperature of from 60 to 90 DEG C with feed of a Ziegler-Natta catalyst system, and, in a second polymerisation zone, at a pressure of from 7 to 35 bar and a temperature of from 40 to 70 DEG C, a mixture of olefins is polymerised onto the finely divided polymer discharged from the first polymerisation zone, is characterised in that, in the second polymerisation zone, a mixture of propylene, ethylene and a further alpha -olefin having 4 to 10 carbon atoms is polymerised on at a ratio between the partial pressures of propylene and ethylene in the range of from 100 : 20 to 100 : 120 and at a ratio between the partial pressures of propylene and the alpha -olefin in the range from 100 : 1 to 100 : 20, the pressure in the second polymerisation zone is chosen to be at least 5 bar below the pressure in the first polymerisation zone, and the weight ratio between the monomers reacted in the first and second polymerisation zones is such that it is in a range between 100 : 10 and 100 : 50.

Abstract: Partly crosslinked plastic materials with MFI 230/21.6 of 0.1-100 g/10 mins. (I) consist of (a) a polymer and (b) a bis-maleimide cpd. of formula (II). (I) are obtd. by reacting (a) with (b) at 180-280 deg.C and 1-100 bar with mean residence time of 0.2-10 mins. (a) comprises (a1) a polymer of 25-97 wt.% propylene copolymer with 0.1-15 wt.% 2-10C alkene units (A) and 3-75 wt.% other propylene copolymer with 15-80 wt.% 2-10C alkene units (B) or (a2) a polymer of 25-97 wt.% propylene homopolymer (C) and 3-75 wt.% (B) or (a3) a statistical copolymer of propylene with less than 15 wt.% 2-10C alkene units, or (a4) propylene homopolymer with MFI of 0.01-100 g/10 mins.
