Abstract:
1. A heterophasic alpha-olefin random copolymer composition comprising (a) an alpha-olefin random copolymer component (A) of at least two alpha-olefin copolymer fractions (i) and (ii), and (b) a rubber component (B) which is an elastomeric alpha-olefin copolymer, wherein component (A) is a R/R-matrix wherein fraction (i) is a copolymer fraction comprising a copolymer of an alpha-olefin with one or more alpha-olefin comonomers and (ii) is a copolymer; the comonomer content (wt %) of fraction (i) is different from the comonomer content (wt %) of fraction (ii), and the heterophasic alpha-olefin random copolymer composition has a melting temperature (T m ) of at least 130° C. but not higher than 155° C., xylene soluble content from 30 to 70 wt %, and a flexural modulus between 100 to 600 MPa.
