FIELD: chemistry.

SUBSTANCE: invention relates to an adhesive composition based on polyethylene, intended for use as an adhesive layer in multilayer articles. Composition contains from 5 to 45 wt% low-pressure polyethylene; from 20.87 to 83.97 wt% of one or two linear low-pressure polyethylenes, representing an ethylene homopolymer or copolymer of ethylene and (C4-C8)-α-olefin with content of α-olefin comonomer 1.5-8 wt%, from 10 to 30 wt% copolymer of ethylene and (C4-C8)-α-olefin with content of α-olefin comonomer 10-40 wt%, functional monomer, preferably maleic anhydride, organic peroxide; vaseline oil and from 0.5 to 2 wt% of 5 % segregation-promoting additive concentrate. Composition is obtained by mixing components in melt in an extrusion or capacitive mixing equipment using a single-step or double-step method.

EFFECT: obtained adhesive composition based on polyethylene has high adhesion strength.
