FIELD: technological processes; chemistry.
SUBSTANCE: invention relates to a multilayer structure comprising a polyolefin layer and a polyamide polymeric composite layer. Polyamide composite layer comprises a polyamide polymer in which the diamine unit constituting it comprises a structural unit derived from xylylenediamine, and its dicarboxylic structural unit includes a structural unit-derivative an α,ω-unbranched aliphatic dicarboxylic acid containing from 4 to 20 carbon atoms, as well as a modified polyolefin, wherein the content of the modified polyolefin is from 5 to 30 parts by mass with respect to 100 parts by mass of the polyamide polymer of the composite layer.
EFFECT: this multi-layered structure has excellent flexibility and fuel-resistance properties and is intended for use as a water pipe.
