A polyolefin composition made from or containing:n A) from 55 to 75 wt % of a polyethylene having a density of 0.920 to 0.940 g/cm 3 and a fraction soluble in xylene (XS A ) of less than 10%, based upon the weight of the polyethylene; B) from 25 to 45 wt. % of a copolymer of ethylene with one or more comonomers selected from α-olefins having formula HC 2 ═CHR I , where R I is an alkyl radical, linear or branched, having from 1 to 8 carbon atoms, made from or containing from 50 to 70 wt. %, based upon the weight of the copolymer of ethylene, of ethylene and having a fraction soluble in xylene (XS B ) of at least about 50 wt. %, based upon the weight of the copolymer of ethylene;n nthe polyolefin composition having a flexural modulus of less than 260 MPa as measured according to ISO 178. The polyolefin composition is useful for producing geomembranes. |
