Title:
THERMOPLASTIC ELSATOMER COMPOSITION, AND PNEUMATIC TIRE USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/026167
Kind Code:
A1
Abstract:
Provided is a thermoplastic elastomer composition suitable for use as an inner liner of a pneumatic tire, and exhibiting excellent air barrier properties and fatigue endurance. The thermoplastic elastomer composition has a rubber composition dispersed in a thermoplastic resin composition, said rubber composition containing a halogenated isoolefin para-alkylstyrene copolymer and being crosslinked, and said thermoplastic resin composition containing a polyamide and an ethylene vinyl alcohol copolymer/polyvinyl alcohol. The amount of the ethylene vinyl alcohol copolymer/polyvinyl alcohol is preferably 1-25 mass% of the total amount of the thermoplastic resin composition. The amount of the halogenated isoolefin para-alkylstyrene copolymer is preferably 80-200 parts by mass to 100 parts by mass of the total of the thermoplasic resin composition.
