Patent

CA 2631734

The invention provides for processes to produce elastomeric compositions, the processes including contacting at least one elastomer with a processing aid, wherein the processing aid includes the reaction product of at least one functionalized polymer having at least one anhydride group contacted with at least one polyamine, wherein the at least one polyamine includes at least one primary amine. The invention also provides for articles such as innerliners for tires produced from the aforementioned elastomeric compositions.

L'invention concerne des procédés de production de compositions élastomères, ces procédés consistant à mettre en contact au moins un élastomère avec un adjuvant. Ledit adjuvant comprend le produit de réaction d'au moins un polymère fonctionnalisé comportant au moins un groupe anhydride mis en contact avec au moins une polyamine, cette ou ces polyamines comprenant au moins une amine primaire. L'invention concerne également des articles, tels que des revêtements intérieurs de pneus, produits à partir des compositions élastomères susmentionnées.
