    摘要: The present invention concerns heterophasic propylene copolymers, comprising a propylene homopolymer (PPH) and an ethylene-propylene rubber (EPR), having a very broad molecular weight distribution, a well-defined total ethylene content and a specific intrinsic viscosities of the ethylene-propylene rubber (EPR). The invention further concerns the process to produce such heterophasic propylene copolymers. The heterophasic propylene copolymers of the present invention are particularly suited for pails, pallets, IBCs and crates. In particular, the heterophasic propylene copolymers of the present invention are characterized by an improved resistance to creep.

    摘要: The present invention relates to a process for the production of propylene homo- and copolymers having a broad molecular weight distribution and a low ash content, with “ash” denoting aluminium as well as residues of catalyst, cocatalyst or any additive, such as titanium (Ti) or silicium (Si) derivatives, used in the production of propylene polymers. The propylene polymers of the present invention are useful to make films, such as capacitor films, as well as fibers and nonwovens, such as for example staple fibers, spunbond nonwovens, meltblown nonwovens.
