Pneumatic tire having an innerliner of a rubber composition which contains a low molecular weight trans 1,4-polybutadiene rubber

   
   

The present invention relates to a pneumatic rubber tire having an integral innerliner of a rubber composition comprised of butyl rubber and/or halogenated butyl rubber and low molecular weight trans 1,4-polybutadiene rubber, wherein said rubber composition may also contain a minor amount of at least one additional, sulfur curable, elastomer.

A invenção atual relaciona-se a um pneu de borracha pneumático que tem um innerliner integral de uma composição de borracha compreendida da borracha butyl e/ou da borracha butyl halogenated do borracha e a baixa do peso molecular do transporte 1,4-polybutadiene, wherein a composição de borracha dita pode também conter uma quantidade menor ao menos de uma adicional, enxôfre curable, elastomer.
