Abstract:
Polypropylene composition comprising propylene homopolymer (H-PP) and a propylene copolymer (C-PP), said copolmyer comprises (a) a propylene copolymer fraction (A) having a comonomer content of equal or above 1.0 wt.-%, the comomers are C5 to C12 α-olefins, and (b) a propylene copolymer action (B) having a comonomer content of 4.0 to 20.0 wt-%, the comomers are C5 to C12 α-olefins, wherein further (i) the comonomer content in propylene copolymer fraction (A) is lower compared to the comonomer content in the propylene copolymer fraction (B), (ii) the propylene copolymer (C-PP) has a comonomer content of at least 2.0 wt.-%, the comomers are C5 to C12 α-olefins, (iii) the weight ratio [(A)/(B)] of the propylene copolymer fraction (A) to the propylene copolymer fraction (B) is in the range of 20/80 to 80/20, and (iv) the weight ratio [(C-PP)/(H-PP)] of the propylene copolymer (C-PP) to the propylene homopolymer (H-PP) is in the range of 95/5 to 75/25.
