    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: The present invention is directed to a heterophasic polypropylene composition with improved sterilization resistance and optical properties for blow molding applications, in particular for use in the blow-fill-seal process for preparing bottles. The present invention is further directed to a process for producing such a polypropylene composition using a single-site catalyst and to a container produced from such a polypropylene composition by blow molding, like a bottle, in particular a blow-fill-seal bottle, with improved haze before and after sterilization. The polypropylene composition comprises 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 0.5 to 20.0 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 940 kg/m3, wherein the xylene cold solubles (XCS) content of the polypropylene composition is from 5.0 to 30.0 wt %.

    Abstract: The present invention relates to crosslinkable polyolefin compositions, to a process for their preparation, to crosslinked compositions such as foams, sealants or adhesives and shaped articles, and their use in food packaging, textile packaging and technical and protection films. The crosslinkable polyolefin composition comprises one or more polyolefin polymers A, a hydrolysable silane functional polyolefin polymer B prepared from monomers comprising olefin monomers a) and silane functional compound(s) b), wherein the silane functional polyolefin polymer B is grafted onto the one or more polyolefin polymers A. The crosslinkable polyolefin compositions is crosslinkable by moisture.
