The present invention is directed to a heterophasic polypropylene composition (HECO1) and the use thereof to reduce the amount of flow marks of an injection moulded polyolefin composition. Further, the present invention is directed to a polyolefin composition (C) comprising a polyolefin (PO), said heterophasic polypropylene composition (HECO1) and optionally a filler as well as an article comprising said polyolefin composition (C).

Polyolefin composition with improved surface appearance

A process for producing copolymers of ethylene and at least one alpha-olefin having from 4 to 10 carbon atoms in the presence of a solid Ziegler-Natta catalyst comprising of magnesium, titanium, halogen and an internal organic compound, the copolymer having a density of from 906 to 937 kg/mand a melt flow rate MFRmeasured at 190&#xb0; C. under 21.6 kg load of from 3 to 150 g/10 min. The process includes the steps of (A) homopolymerising ethylene or copolymerising ethylene and a first alpha-olefin having from 4 to 10 carbon atoms in a first polymerisation stage in the presence of the polymerisation catalyst, hydrogen and optionally the first alpha-olefin; (B) copolymerising ethylene and a second alpha-olefin having from 4 to 10 carbon atoms in a second polymerisation stage in the presence of the first homo- or copolymer of ethylene and the Ziegler-Natta catalyst; and (C) recovering the polymer mixture.

Process for producing LLDPE resins

This invention relates to a thermoplastic polyolefin composition having a melt flow rate MFR(230&#xb0; C.) between 20 and 100 g/10 min, to the use of such thermoplastic polyolefin composition for the production of injection molded articles, e.g. automotive parts and to injection molded articles prepared by using such thermoplastic polyolefin composition.

High flow thermoplastic polyolefin with balanced mechanical performance and low shrinkage and CLTE
