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.
