Abstract: The present invention provides a soft multimodal random heterophasic polypropylene composition (m-Raheco) with improved stiffness and impact behaviour while maintaining optical properties. The multimodal random heterophasic polypropylene composition (m-Raheco) is suitable as material for injection moulding, e.g. for thin walled injection moulded articles. The present invention also describes specific propylene random copolymers as modifiers or compatibilizers in polyolefins and their according use.

Abstract: A process for the preparation of a polypropylene in a sequential polymerization process including at least two polymerization reactors connected in series. The polymerization takes place in the presence of a Ziegler-Natta catalyst, and said 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 ratio of catalyst feed rate to propylene feed rate in the first polymerization reactor is 1.0 to 4.5 g/t.
