Abstract: front page image
(EN)An elastomeric composition incorporating a hydrocarbon polymer modifier including piperylene, cyclic pentadiene and aromatic components, and having a softening point from 80°C to 160°C, z-average molecular weight greater than 10,000, and at least 1 mole percent aromatic hydrogen, based on the total moles of hydrogen in the modifier. In a method, the elastomeric composition is processed with a cure package into a composition in the desired shape, which is cured to form the article. The modifier may optionally be immiscible with an elastomer in the composition and/or co-cured with the elastomer or filler in the composition. A tire or tire component may include the elastomeric composition.
(FR)L'invention concerne une composition élastomère incorporant un modificateur polymère hydrocarboné incluant un pipérylène, un pentadiène cyclique et des composants aromatiques, et de point de ramollissement compris entre 80 °C et 160 °C, de masse moléculaire moyenne Z supérieure à 10 000, et au moins 1 % molaire d'hydrogène aromatique par rapport au nombre de moles total d'hydrogène dans le modificateur. Dans un procédé, la composition élastomère est transformée avec un mélange durcisseur en composition de forme souhaitée, cette dernière étant ensuite durcie pour former l'article. Le modificateur peut éventuellement être immiscible à un élastomère de la composition et/ou co-durci avec l'élastomère ou la charge de la composition. Un pneumatique ou élément de pneumatique peut inclure la composition élastomère.
