PNEUMATIC TIRE COMPRISING A FILM COMPOSED OF A THERMOPLASTIC ELASTOMER COMPOSITION AS INNER LINER

摘要

An object of the present invention is, in a thermoplastic elastomer composition in which a modified rubber is dispersed and filled in an ethylene-vinyl alcohol copolymer matrix in order to improve the low-temperature durability of the ethylene-vinyl alcohol copolymer, to reduce the extrusion load during extrusion molding thereof into a film without deteriorating the low-temperature durability. The present invention is a thermoplastic elastomer composition comprising an ethylene-vinyl alcohol copolymer (A) and a modified rubber (B) dispersed in the ethylene-vinyl alcohol copolymer (A), wherein the modified rubber (B) has an acid anhydride group or epoxy group and is dynamically cross-linked by a compound (C) having at least two amino groups. This thermoplastic elastomer composition can be suitably used in the production of an inner liner of a pneumatic tire.
