1. the purposes of composition in the pipe for transfer oil product or gas, wherein said composition comprises, the gross weight relative to it:

  • The polyethylene for grafting functionalized monomer of 1-40% or polyethylene (A1) and the blend (A) of second polymer (A2) being different from (A1), the wherein unsaturated functionalized monomer of this blend cografting of (A1) and (A2), for (A), the weight content of unsaturated functionalized monomer is within the scope of 30-100000 ppm;

    25-98% has from being greater than the non-grafted polyethylene (B) obtained by metallocene catalyst that 0.925 to 0.965 comprises the density of the scope of this cut off value;

    The resilient material product (C) of 1-35%, it is selected from ethene-(methyl) alkyl acrylate copolymer or ethene-(methyl) alkyl acrylate-maleic anhydride terpolymer.
