INNER LINER FOR PNEUMATIC TIRE, METHOD FOR PRODUCING THE SAME, AND PNEUMATIC TIRE

摘要

Provided is an inner liner for a pneumatic tire including no less than 8 resin-layers, the resin-layer having a layer A constituted with a resin composition containing a resin having gas barrier properties, and a layer B that is adjacent to the layer A and is constituted with a resin composition containing an elastomer, an extensional viscosityηA of the resin composition of the layer A, and an extensional viscosityηB of the resin composition of the layer B as determined at a predetermined temperature both being no less than 1,000 Pa·s, and an extensional viscosity ratioηA/ηB being no less than 0.2 and no greater than 10.
