Abstract
The invention relates to a heterophasic alpha-olefÊn random copolymer composition with a melting temperature (Tm) of at least 130° C. and a flexural modulus of not higher than 1000 MPa5 whereby the inventive composition comprises an al-pha-olefin random copolymer component (A) of at least two alpha-olefÊn (co)polymer fractions (i) and (ii) having a different comonomer content, whereby at least one of the fractions is an alpha-olefÊn random copolymer, and a rubber component (B).
