Abstract:
A laminate (C) of a thermoplastic polymer composition comprising: a thermoplastic resin composition (A) having an permeation coefficient of 10×10−12 cc·cm/cm2·sec·cmHg or less, laminated with a thermoplastic polymer composition (B) having a melt viscosity of 500-2000 Pa·s and a Young's modulus at a room temperature of 1-400 MPa, wherein the thickness of a layer of the thermoplastic resin composition (A) is 0.05-10 μm and the air permeation coefficient of the laminate (C) of 20×10−12 cc·cm/cm2·sec·cmHg or less, and a pneumatic tire using the above laminate (C) as an inner liner.
