Abstract: A process for the preparation of a polypropylene in a sequential polymerization process including a pre-polymerization reactor and at least two polymerization reactors connected in series. The polymerization in the at least two polymerization reactors takes place in the presence of a Ziegler-Natta catalyst. The Ziegler-Natta catalyst includes (a) a pro-catalyst that has a compound of a transition metal, a compound of a metal which metal is selected from one of the groups 1 to 3 of the periodic table (IUPAC), and an internal electron donor, (b) a co-catalyst, and (c) an external donor. The Ziegler-Natta catalyst is present in the pre-polymerization reactor. Ethylene and propylene are fed to the pre-polymerization reactor in a feed rate ratio of 0.5 to 10.0 g/kg.

Abstract: This invention relates to a thermoplastic polyolefin composition having a melt flow rate MFR2 (230° C.) between 20 and 100 g/10 min, to the use of such thermoplastic polyolefin composition for the production of injection moulded articles, e.g. automotive parts and to injection moulded articles prepared by using such thermoplastic polyolefin composition.

Abstract: Heterophasic polypropylene copolymers having an MFR (2.16 kg, 230° C.) of 15 to 200 g/10 min, determined according to ISO 1133 comprising a propylene homo- or copolymer matrix with an MFR (2.16 kg, 230° C.) of 80 to 500 g/10 min, determined according to ISO 1133 (A) and an ethylene or C4-C10-alpha-olefin propylene rubber phase (B) dispersed within the matrix, wherein the heterophasic polypropylene resin has a fraction soluble in p-xylene at 25° C. (XCS), having an intrinsic viscosity of 2.85 to 4.00 dl/g, determined according to DIN EN ISO 1628-1 and -3 and being composed of propylene monomer units in an amount of 70 wt % to 90 wt %, with optimum balance of impact resistance and low amount of hexane extractables; a process for their preparation and their use.

Abstract: A trolley (30) for use with a frame-straightening bench (10) and allowing for moving a vehicle into the bench (10) for initial repair; moving the vehicle out of the bench (10) and into a holding area to allow for curing or other time-consuming repair processes or operations, thereby making the bench (10) available for other uses; and moving the vehicle back into the bench (10) for additional repair or final confirmation of a previous repair. A repair jig (140) is coupleable with the trolley (30) for facilitating the alignment and otherwise proper positioning of a portion of the vehicle being repaired. The trolley (30) can also be used with a lift (2072) to separate the vehicle's body from its frame (2010).
