LAMINAR STRUCTURE WITH LOW MOISTURE PERMEABILITY Russian patent published in 2011 - IPC B32B25/08 B32B27/04 B60C1/00 

FIELD: construction.

SUBSTANCE: laminar structure for use in products includes three layers, one of which is a layer that prevents penetration of fluid medium, having the upper and lower surfaces, and containing a polymer composition that consists of a thermoplastic component and an elastomer component, which in the vulcanised form is dispersed as a discrete phase in the matrix of the thermoplastic polymer component. The second layer of the laminar structure is a thermoplastic layer, which forms a laminar structure with the lower surface of the layer, which prevents penetration of fluid medium and contains a film-forming semicrystalline polymer with a carbon chain with glass transition temperature T_g of less than approximately -20°C. The structure also comprises a layer including rubber with high content of diene, forming a laminar structure with the upper surface of the layer, which prevents penetration of fluid medium.

EFFECT: invention makes it possible to increase strength of product with low permeability of fluid medium.
