Patent ID: 8056595

Claim:
A low permeability rubber laminate comprising a low permeability resin composition (A) layer having an air permeation coefficient, determined according to JIS K7126, of 0.5Ã—10 âˆ’12 ccÂ·cm/cm 2 Â·secÂ·cmHg or less at 30Â° C., an average thickness d of 0.05 Î¼m<d<20 Î¼m and a Young's modulus E of 0.5 MPa<E<300 MPa at 200Â° C. and a rubber composition (B) layer, laminated together, wherein the low permeability resin composition (A) comprises (i) 100 parts by weight of an ethylene vinyl alcohol copolymer (D) having an ethylene composition ratio of 20 to 50 mol % and a saponification degree of 90% or more, (ii) 10 to 100 parts by weight of an aliphatic polyamide resin (E) having a melting temperature, found from an endothermic peak of a differential scan calorimeter (DSC), of higher than 200Â° C. and (iii) 5 to 100 parts by weight, based upon 100 parts by weight of the total amount of the ethylene vinyl alcohol copolymer (D) and polyamide resin (E), of a modified ethylene-based copolymer (F) and has a phase structure containing the modified ethylene-based copolymer (F) as a dispersed particle phase.
