POLYOLEFIN COMPOSITION FOR ROOFING APPLICATIONS
A polyolefin composition made from or containing:(A) 18-35% by weight of a copolymer of propylene with an alpha-olefin, wherein the copolymer contains 2.0-4.0% by weight of the alpha-olefin and has a melt flow rate (MFRA) ranging from 30 to 60 g/10 min; and(B) 65-82% by weight of a copolymer of propylene with an alpha-olefin, and optionally a diene, wherein the copolymer is made from or containing 20-35% by weight of the alpha-olefin, whereinthe polyolefin composition is made from or containing a fraction that is soluble in xylene at 25° C. (XS(tot)) in an amount higher than 70% by weight;the amounts of (A), (B), and the fraction soluble in xylene at 25° C. (XS(tot)) are based on the total weight of the polyolefin composition; andthe melt flow rate (MFR) of the polyolefin composition ranges from 0.2 to 2.0 g/10 min.
