ADHESIVE COMPOSITION CONTAINING GRAFTED POLYETHYLENE |
摘要 |
<p>The invention relates to an adhesive composition comprising, relative to its total weight: from 1 to 40% of a polyethylene (A) grafted with a functional monomer or a blend of a polyethylene (A1) with a second polymer (A2) different from (A1), said blend of (A1) and (A2) being co-grafted with an unsaturated functional monomer, the content by weight of unsaturated functional monomer relative to (A) being in the range from 30 to 100000 ppm; from 25 to 98% of a non-grafted polyethylene (B) having a density in the range from 0.900 to 0.965; from 1 to 35% of an elastomeric product (C). The invention also relates to a multilayer structure comprising this composition, said structure being able to serve as protection of metal tubes used for the fabrication of oil pipelines and gas pipelines.</p> |
