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.
