    摘要： A high-density polyethylene (HDPE) can be adapted for the manufacture of caps and closures. The caps and closures can be used as screw-on caps for carbonated or still drinks. The high-density polyethylene can have a density of at least 940 kg/m3 and of at most 970 kg/m3, and a high load melt index HLMI of at least 35 dg/min and of at most 180 dg/min. The high-density polyethylene can include a first polyethylene fraction and a second polyethylene fraction. The first polyethylene fraction can have a density of at least 920 kg/m3 and of at most 945 kg/m3, and a melt index HL275 of at least 3 dg/min and of at most 12 dg/min. The second polyethylene fraction can have a density of at least 960 kg/m3 and of at most 980 kg/m3.

    摘要： A catalyst system can include a Ziegler-Natta catalyst, an internal donor, a magnesium halide in active form, and an organoaluminium compound. The Ziegler-Natta catalyst can have a titanium compound and at least one titanium-halogen bond. The internal donor can include at least 80 wt % of an enamino-imine with respect to a total weight of the internal donor. The Ziegler-Natta catalyst and the internal donor can both be supported on the magnesium halide in active form.

    摘要： The present invention relates to a polypropylene composition comprising: a first polypropylene homopolymer or random copolymer (PPR1) having a comonomer content lower than the comonomer content of the second polypropylene, a second polypropylene (PPR2) which is a random copolymer of propylene and of the comonomer; said comonomer being an alpha-olefin different from propylene, the melting temperature of the polypropylene composition (Tm(PPR)) being defined as Tm(PPR)>165−6.9*[total comonomer content]−8.4*[comonomer content of the first polypropylene], the difference between the melting temperature and the crystallization temperature of the polypropylene composition ranges from 27 and 33, and a xylene soluble fraction (XS) at 23° C. of not more than 1.5 wt. %. The present invention also relates to a process for the preparation of said polypropylene composition. The present invention further relates to the use of said polypropylene composition for producing films or moulded articles.
