Patent ID: 6884846

Claim:
A composition comprising: 99 to 50% by weight of isotactic polypropylene homo- or copolymer obtained by metallocene catalysis (A); 50 to 1% of a polymer or a blend of polymers, the polymer or blend of polymers comprising (i) from 50 to 100% by weight of isotactic polypropylene homo- or copolymer obtained by Ziegler-Natta catalysis (B) grafted by a functionalized monomer; and (ii) from 0 to 50% by weight of a polymer (C) comprising a poly(1-butene) homo- or copolymer (C1), a polystyrene homo- or copolymer (C2), or a polyethylene homo- or copolymer (C3) and their blends, said polymer (C) being itself grafted by a functionalized monomer, the percentages being based on the total of the polymers (A), (B) and (C).
