Abstract: Disclosed is a polyolefin composition comprising: (A) 10-40% by weight of a copolymer of propylene with hexene-1 comprising 1.0-6.0% by weight, based on the weight of (A), of units deriving from hexene-1 and having melt flow rate (MFRA) measured according to ISO 1133, 230°C, 2.16 kg ranging from 20 to 60 g/10 min.; and (B) 60-90% by weight of a copolymer of propylene with at least one alpha-olefin of formula CH2=CHR, and optionally a diene, where R is H or a linear or branched C2-C8 alkyl and wherein the copolymer comprises 20-35% by weight, based on the total weight of (B), of alpha-olefin, wherein the polyolefin composition comprises an amount of fraction soluble in xylene (XS(tot)) at 25°C equal to or higher than 65% by weight, the amounts of (A), (B) and XS(tot) being based on the total weight of (A)+(B). The polyolefin composition finds use in roofing application and in the productions of geomembranes.
