A polyolefin composition made from or containing: (I) 50-95% by weight of a heterophasic polyolefin composition made from or containing: (A) 10-40% by weight of a propylene polymer selected from the group consisting of propylene homopolymers and copolymers of propylene with an alpha-olefin, having 1.0-6.0% by weight of units deriving from the alpha-olefin, wherein the propylene polymer (A) having a melt flow rate (MFRA) ranging from 20 to 60 g/10 min.; and (B) 60-90% by weight of a copolymer of propylene with an alpha-olefin, having 20-35% by weight of units deriving from the alpha-olefin, wherein the fraction of the heterophasic polyolefin composition (I) soluble in xylene at 25° C. (XS(I)) is equal to or higher than 60% by weight; and (II) 5-50% by weight of a propylene-ethylene copolymer having 12-25% by weight of units deriving from ethylene.
A polyolefin composition comprising:
A method for preparing a heterophasic polyolefin composition (I) comprising a propylene polymer (A) and a copolymer of propylene (B), comprising the step of:
