    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: The present invention is directed to a heterophasic polypropylene composition of high transparency based on excellent compatibility of the propylene 1-hexene random copolymer used as matrix with different types of external modifiers dispersed within the matrix. The present invention is further directed to a process for producing such a polypropylene composition and to a film, in particular a cast film, obtained from such a polypropylene composition. The polypropylene composition comprising a blend of a propylene copolymer comprising 2.5 to 12.0 wt % of 1-hexene as a comonomer, and having a melt flow rate MFR2 of 0.1 to 100 g/10 min, and an ethylene homo- or copolymer having a melt flow rate MFR2 of 0.05 to 30.0 g/10 min and a density of 850 to 920 kg/m3, wherein the melt flow rate MFR2 of the polypropylene composition is from 1.0 to 12.0 g/10 min.

    Abstract: New C2C3 random copolymer (RACO), which shows improved sealing behaviour due to low sealing initiation temperature (SIT) and high hot tack force. In addition, the inventive C2C3 random copolymer (RACO) shows an excellent sterilization behaviour, i.e. retention of low haze level after sterilization. The present invention is furthermore related to the manufacture of said C2C3 random copolymer (RACO) and to its use.
