Zusammenfassung:FIELD: process engineering. ^ SUBSTANCE: invention relates to vulcanised multilayer structures, for example automotive tires. Proposed structure comprises at least two layers and at least one jointing layer. First of two layers inhibits fluid penetration. Second layer comprises at least one rubber with high content of diene. Jointing layer consists of the following mix: (1) 50-90 wt % of at least one halogenated isobutylene-containing elastomer; (2) 5-50 wt % of at least one elastomer with high content of diene; (3) 20-50 wt % of at least one filler; (4) 0-30 wt % of at least one process oil, and (5) 0.2-15 parts per 100 parts of rubber of vulcanising system for elastomer.Rubber and elastomer with high content of diene contain at least 50 mol % of diene monomer. Layer that inhibits fluid penetration comprises polymer composition with air permeability factor equal to 25x10-12 cu cmcm/cm2 s cm Hg (at 30C) or less, and Young module equal to 1 - 500 MPa. Said polymer composition comprises: (A) at least, 10 wt % of total weight of composition of at least one thermoplastic synthetic polymer component with air permeability factor equal to 25x10-12 cu cm-cm/cm2 s cm Hg (at 30C), and Young module exceeding 500 MPa. Thermoplastic synthetic polymer component is selected from the group consisting of resins: polyamide, polyester, polynitrile, polymethacrylate, polyvinyl, imide polymers of cellulose and fluorinated polymers. Polymer composition comprises also (B) at least, 10 wt % of total weight of composition of at least one thermoplastic synthetic polymer component with air permeability factor exceeding 25x10-12 cu cmcm/cm2 s cm Hg (at 30C), and Young module not exceeding 500 MPa. Component (B) is dispersed in vulcanised or partially vulcanised state ad a discrete phase in the matrix of component (A) of polymer composition. ^ EFFECT: reduced permeability for air and better adhesion. ^ 23 cl, 1 dwg, 5 tbl Изобретение относится к вулканизуемой многослойной конструкции в изделиях, удерживающих текучую среду, например, конструкции автошины. Конструкция содержит, по крайней мере, два слоя и, по крайней мере, один соединительный слой. Первый из двух слоев препятствует проникновению текучей среды. Второй слой содержит, по крайней мере, один каучук с высоким содержанием диена. Соединительный слой состоит из смеси: (1) от 50 до 95 мас.%, по крайней мере, одного галогенированного изобутилен-содержащего эластомера; (2) от 5 до 50 мас.%, по крайней мере, одного эластомера с высо
