  • Polyolefin compositions having high tenacity
    Patent number: 6743864
    Abstract: A polyolefin composition suitable for preparing single ply roofing membranes, comprising: (A) from about 15 to about 40% by weight of a crystalline copolymer of propylene with at least one alpha-olefin of formula H2C═CHR1, where R1 is H or a C2−8 linear or branched alkyl, containing at least about 90% by weight of propylene, having solubility in xylene at room temperature lower than about 15% by weight; (B) from about 60 to about 85% by weight of an elastomeric fraction comprising: (1) a copolymer of propylene with ethylene containing about 20 to about 35% by weight ethylene, and having solubility in xylene at room temperature greater than about 70% by weight, the intrinsic viscosity of the xylene soluble fraction being higher than about 3.0 dl/g up to about 6.
