Abstract: The invention concerns a method of producing multi-phase block copolymers, the method being characterized in that, in the gas phase, in the presence of a metalocene catalyst system at temperatures of -50 to +300 DEG C and pressures of 1 to 1000 bar: a) as a first step, 45 to 95 % by wt. of a polymer matrix (A) comprising an alk-1-ene homopolymer or copolymer with a comonomer content of up to 10 % by wt. relative to the matrix (A) is produced and b) as a second step, in the presence of the matrix (A) obtained in step (a), b1) o.5 to 97 % by wt. of at least one alk-1-ene having at least 3 C-atoms and b2) 3 to 99.5 % by wt. of ethylene is reacted to give 5 to 55 % by wt. of a copolymer phase (B).

Abstract: A process is disclosed for producing homopolymers of propylene or copolymers of propylene with other olefins or their mixtures. Polymerisation is carried out under pressures from 100 to 3000 bars and at temperatures from 100 to 330 DEG C, using as catalyst a metallocene catalyst system.

Abstract: A Ziegler-Natta catalyst system (I) is claimed, contg. (a) a solid component contg. Ti, Mg, Hal and an electron donor, (b) an Al component and (c) an organosilicon cpd. of formula (R1)nSi(OR2)4-n (II) as a further electron donor component; R1 = 3-8 membered cycloalkyl; R2 = 1-8C alkyl; n = 1, 2 or 3. Pref., R1 = 5-7 membered cycloalkyl, R2 = 1-4C alkyl and n = 2. USE/ADVANTAGE - (I) is useful for the polymerisation of olefins. The claims include: (i) a process for the polymerisation of propylene at 20-150 deg.C and 1-100 bar with (I) as catalyst system, (ii) polymers of propylene obtd. by this process and (iii) films and moulded prods. made from these polymers. The use of (I) enables the polymerisation of propylene with high productivity, to give PP with a high degree of sterospecificity and very low halogen content. (6pp Dwg.No.0/0)
