Title:
THERMOPLASTIC ELASTOMER COMPOSITION AND PNEUMATIC TIRE PREPARED THEREFROM
Document Type and Number:
Japanese Patent JP3640467
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a thermoplastic elastomer compsn. excellent in the adhesion to a rubber layer and most suitable for an air-impermeable layer of a pneumatic tire by using a compsn. comprising a continuous thermoplastic resin phase containing a specified adhesive thermoplastic resin and a dispersed elastomer phase.
SOLUTION: This composition comprises (A) at least 10wt.% continuous phase comprising at least one thermoplastic resin having a coefficient of air permeation of 25×10-12cc.cm/cm2.sec.cmHg or below and a Young's modulus of above 500MPa, (B) at least 10wt.% dispersed phase comprising at least one elastomer having a coefficient of air permeation of 25×10-12cc.cm/ cm2.sec.cmHg or below and a Young's modulus of 500MPa or below, and (C) the component (A) further containing 1 to 75wt.% adhesive thermoplastic resin having a volume fraction × visosity ratio to the thermoplastic resin (A) of the formula and also having a coefficient of air permeation of 25×10-12cc.cm/cm2.sec.cmHg or below and a Young's modulus of not above 500MPa.
