Propylene homo- or copolymer composition comprising an in-situ reactor blend of a Ziegler-Natta catalysed, nucleated polypropylene (znPP) and a metallocene catalysed polypropylene (mcPP), in a weight ratio in the range of 6:94 to 50:50 (wt % znPP:wt % mcPP), preferably in the range of 10:90 to 44:56 (wt % znPP:wt % mcPP), having an excellent balance between optical properties, mechanical properties, thermal properties and processing properties; a process for its production and the use of a mixture of a Ziegler-Natta catalyst system and a metallocene catalyst system.

In-situ reactor blend of a Ziegler-Natta catalysed, nucleated polypropylene and a metallocene catalysed polypropylene

The present invention relates to a polypropylene which has&#x2014;a melt flow rate MFR(230&#xb0; C., 2.16 kg) of at least 13 g/10 min,&#x2014;an amount of xylene solubles XS of 6.0 wt % or less, and&#x2014;a crystalline fraction, wherein at least 10% of the crystalline fraction melts the temperature range of from 160 to 170&#xb0; C., as determined by the stepwise isothermal segregation technique (SIST).

Polypropylene with living hinge properties

A multimodal ethylene copolymer with a density of at least 940 kg/mhaving an MFRin the range of 1 to 30 g/10 min and a F/&#x3bb;ratio of less than 60 cN/s; said ethylene copolymer comprising at least three components (I) an ethylene and optionally at least one C3-20 alpha olefin comonomer component forming 30 to 60 wt % of said ethylene copolymer; (II) an ethylene and optionally at least one C3-20 alpha olefin comonomer second component forming 30 to 60 wt % of said ethylene copolymer: and (III) an ethylene and optionally at least one C3-20 alpha olefin comonomer third component forming 3 to 20 wt % of said ethylene copolymer; wherein at least one of components (II) or (III) is a copolymer.

Multimodal polymer

The present invention relates to a heterophasic polypropylene resin comprising a crystalline propylene homopolymer matrix (A) and an amorphous propylene copolymer phase (B) dispersed within the matrix having excellent mechanical properties, in particular at low temperatures, and at the same time high flowability. Further, the invention relates to a production process of the heterophasic polypropylene resin, the use of such a resin in a polypropylene composition and to articles made of the heterophasic polypropylene resin.

Heterophasic polypropylene with high flowability and enhanced mechanical properties

The present invention relates to a high flow polypropylene composition comprising (A) a low molecular weight propylene homopolymer fraction and (B) a high molecular weight propylene copolymer fraction, having a comonomer content of not higher than 8 wt %, wherein the ratio between the MFRof fraction (A) and the MFRof fraction (B) is at least 3 and wherein the MFRof the entire composition is at least 5 g/10 min, the values of MFRbeing measured according to ISO 1133 (230&#xb0; C., 2.16 kg load), and to processes for producing such compositions and to articles made there from.
