Zusammenfassung:	Semicrystalline polyolefin composition comprising (by weight): A) 20-60% of a propene/C4-Cl0 alpha -olefin random copolymer (Fraction A), containing from l to l0% of a C4-Cl0 alpha -olefin, B) 40-80% of a propene/C4-Cl0 alpha -olefin random copolymer (Fraction B), containing from l5 to 40% of a C4-Cl0 alpha -olefin, same or different from the one present in Fraction A, where the percentage by weight of Fraction B (%B), referred to the total composition, and the percentage by weight of C4-Cl0 alpha -olefin in Fraction B (C4) satisfy the following relation: %B . C4 >/= l200. o
