Polymer composition for tire and pneumatic tire using same |
摘要 |
<p>A polymer composition for a tire having an air permeation coefficient of 25 x 10<-12> cc.cm/cm<2>.sec.cmHg (at 30 DEG C) or less and a Young's modulus of 1 to 500 MPa, including (A) at least 10% by weight, based on the weight of the total polymer component, of at least one thermoplastic resin having an air permeation coefficient of not more than 25 x 10<-12> cc.cm/cm<2>.sec.cmHg (at 30 DEG C) and a Young's modulus of more than 500 MPa and (B) at least 10% by weight, based on the total weight of the polymer component, of at least one elastomer component having an air permeation coefficient of more than 25 x 10<-12> cc.cm/cm<2>.sec.cmHg (at 30 DEG C) and a Young's modulus of not more than 500 MPa, wherein the total amount (A) + (B) of the component (A) and the component (B) is not less than 30% by weight based on the weight of the total polymer component, and a pneumatic tire obtained therefrom.</p> |
