The invention relates to an adhesive composition including, relative to the total weight thereof: 1 to 40% of a polyethylene (A) grafted by a functional monomer or a mixture of a polyethylene (A1) to a second polyethylene (A2) different from (A1), the mixture of (A1) and (A2) being co-grafted by an unsaturated functional monomer, the weight content of the unsaturated functional monomer relative to (A) being 30 to 100000 ppm; 25 to 98% of an ungrafted polyethylene (B) having a density of 0.900 to 0.965; and 1 to 35% of an elastomer product (C). The invention also relates to a multilayer structure including said composition, the structure being used as protection for metal tubes used in the production of oil and gas pipelines. The present invention provides to make a binder composition with improved adhesion. |
