    Abstract: Ziegler-Natta type catalyst system (ZNC), containing (a) a titanium-based solid component containing compounds of Ti and magnesium, a halogen, an inorganic oxide support (IOS) and a carboxylate ester as electron donor, (b) an aluminium compound and (c) optionally another electron donor, in which the oxide (IOS) has a pH of 1-6, an average particle diameter of 5-200 microns and an average primary particle diameter of 1-20 mu m, and contains pores or channels with an average diameter of 0.1-20 mu m in amounts of 5-30 vol%. Also claimed is (i) a process for the production of ZNC by interacting components (a), (b) and (c) together at 0-150 degrees C and 1-100 bar; (ii) a process for the production of polymers of 2-20C alk-1-enes by polymerisation of the alkene (preferably propylene) and optionally other comonomers at 20-150 degrees C and 1-100 bar in presence of (ZNC); (iii) polymers of propylene obtained by this process.

    Abstract: A process for the preparation of multiphase homopolymers or copolymers of C2-C10-alk-1-enes, characterised in that the polymerisation is carried out in one reaction zone in the presence of two different catalyst systems, where one of the catalyst systems contains, as active constituents, a metallocene complex of the formula (I) or (II) in which M is a metal from group IVb, Vb or VIb of the Periodic Table, R and R are identical or different and are a hydrogen atom, a C1-C10-alkyl group, a C1-C10-alkoxy group, a C6-C10-aryl group, a C6-C10-aryloxy group, a C2-C10-alkenyl group, a C7-C40-arylalkyl group, a C7-C40-alkylaryl group, a C8-C40 arylalkenyl group or a halogen atom, R and R are identical or different and are a hydrogen atom, a halogen atom, a C1-C10-alkyl group, which may be halogenated, a C6-C10-aryl group, an -NR 2, -SR , -OSiR 3, - SiR 3 or -PR 2 radical, in which R is a halogen atom, a C1-C10-alkyl group or a C6-C10-aryl group, and R and R are identical or different and are as defined for R and R with the proviso that R and R are not hydrogen.

    Abstract: Processing Ziegler-Natta (S-N) catalyst systems contg. (a) a Ti-contg. solid component contg. electron donor(s), in the form of a suspension in inert solvent, and as co-catalyst; (b) an Al cpd.; and (c) opt. other electron donor cpds. comprises removing the solvent from suspension (a) by (1) filtering the suspension and then (2) removing more solvent by applying a pressure difference at not above 100 degrees C. Also claimed are the obtd. catalyst systems.
