Abstract: A method for the preparation of 2-12C alpha-olefin polymers at -50 to +300 degrees C and 0.5-3000 bar in the presence of a catalyst system - uses a catalyst that contains the following components :(A) an (in)organic carrier ; (B) a metallocene complex ; (C) a metallocenium ion-forming compound ; and (D) optionally a metal compound of formula (I). M )r(R )s(R )t (I) M = alkali(ne earth) or Group III metal ; R = H, 1-10C alkyl, 6-15C aryl, 1-10C alkyl-(6-20C)-aryl or 6-20C aryl-(1-10C)-alkyl ; R , R = H, halogen, 1-10C alkyl, 6-15C aryl, 1-10C alkyl-(6-20C)-aryl, 6-20C aryl-(1-10C)-alkyl or 1-10C alkoxy ; r = 1-3 ; and s, t = 0-2, with the provision that the sum of r-t is equal to the valency of M . An anti-static agent is also used with the catalyst.

Abstract: Ziegler-Natta-type catalyst system contains (a) a solid component containing titanium (Ti), obtained by reacting a Ti compound with a compound of magnesium (Mg), a halogen, an inorganic oxide as carrier, a 1-8 carbon (C) alkanol and a carboxylic ester as electron donor; and, as co-catalyst, (b) an aluminium (Al) compound and (c) optionally another electron donor compound as active constituents. In the preparation of (a), the individual components are reacted in the presence of an aromatic hydrocarbon as solvent. Also claimed are: (i) a method of producing the catalyst system; (ii) propylene polymers prepared using this catalyst system; and (iii) films, fibres and mouldings made from these polymers. Preferably component (a) is prepared in a 7-12 C alkylbenzene, especially ethylbenzene. The inorganic oxide has a pH of 1-6.5 and average particle diameter of 5-200 mu m and contains 5-30 volume-% pores or ducts with an average diameter of 1-20 mu m. It preferably is spray dried and especially consists of silica gel. The Al compound (b) is a tri-(1-8 C alkyl)-Al compound. Component (c) is an organo-silicon compound of formula R nSi(OR )4-n (I); R = 1-20 C alkyl, 5-7-membered cycloalkyl (optionally mono-substituted by 1-10 C alkyl) or 6-20 C aryl or arylalkyl; R = 1-20 C alkyl; n = 1, 2 or 3.
