FIELD: chemistry.

SUBSTANCE: invention relates to a polyolefin composition for producing an adhesive comprising (A) a first grafted polyolefin composition containing high-density polyethylene (HDPE) grafted with a first unsaturated monomer; (B) a second grafted polyolefin composition containing a first linear low-density polyethylene catalysed by a metallocene grafted with a second unsaturated monomer; (C) a second linear low-density linear polyethylene composition catalysed by a metallocene, having a second linear low-density polyethylene catalysed by a metallocene; (D) a low-density linear low-density polyethylene composition, catalysed by Ziegler-Natta catalysts, comprising linear low-density polyethylene, catalysed by Ziegler-Natta catalysts; (E) an elastomeric composition comprising: (i) an elastomeric copolymer of ethylene containing: (a) derivatives of ethylene; and (b) units of alpha-olefin comonomers derived from at least one comonomer selected from a group consisting of C₃-C₁₀ alpha-olefins; and (ii) ethylene-propylene elastomer; and (F) a hydrocarbon-based adhesion agent.

EFFECT: invention also relates to a multilayer structure containing said adhesive with an adhesive layer and a polymer layer.
