Abstract: The present invention relates to a process for the preparation of a procatalyst suitable for preparing a catalyst composition for olefin polymerization, said process comprising the steps of: Step A) providing or preparing a Grignard compound; Step B) contacting the Grignard compound with a silane compound to give a solid support; Step C) activating said solid support, comprising two sub steps: Step C1) contacting the solid support obtained in step B) with at least one first activating compound and a second activating compound; and Step C2) a second activation step by contacting the partly activated solid support obtained in step C1) with an activating electron donor; to obtain an activated solid support; Step D) reacting the activated solid support obtained in step C) with a halogen-containing Ti compound, optionally an activator and at least one internal electron donor in several sub steps to obtain said procatalyst. The invention moreover relates to a procatalyst, a catalytic system comprising said procatalyst and to a process to prepare polyolefins using said catalyst system and the polyolefins obtained therewith.

Abstract: The invention relates to a polypropylene composition comprising a terpolymer containing propylene, ethylene and 1-hexene wherein the polypropylene composition (i) has a content of ethylene derived units of at least 1.5 wt %; (ii) has a content of 1-hexene derived units of at least 1.5 wt %; (iii) has a melt flow rate of 0.10 to 0.70 g/10 min determined by ISO 1133-1:2011 (230° C., 2.16 kg); and (iv) has a ratio of weight average molecular weight (Mw) to numeric average molecular (Mn) weight of the terpolymer of 7.0 to 20.0, wherein Mw and Mn are measured according to ASTM D6474-12.
