Abstract:
1. A layered construction comprising at least three layers, one of which layers comprising a fluid permeation prevention layer having an upper and a lower surface; at least one thermoplastic layer in laminate relation with at least said fluid permeation prevention layer lower surface, said thermoplastic layer comprising a film-forming semi-crystalline carbon chain polymer having a glass transition temperature, Tg, of less than about −20° C. and wherein said thermoplastic polymer has an equilibrium water content at 100% relative humidity of less than about 0.1 g per 100 g polymer or a molar water content per polymer structural unit of less than about 0.1; and a layer comprising at least one high diene rubber; wherein said fluid permeation prevention layer comprises a polymer composition having an air permeation coefficient of 25×10 (A) at least 10% by weight, based on the total weight of the polymer composition, of at least one thermoplastic resin component having an air permeation coefficient of 25×10 (B) at least 10% by weight, based on the total weight of the polymer composition, of at least one elastomer component having an air permeation coefficient of more than 25×10 wherein said at least one thermoplastic layer comprises low density polymer of ethylene.
