Abstract
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.
