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.
Claims20
A process to produce an elastomeric composition, the process comprising contacting at least one elastomer with a processing aid having a viscosity in the range of greater than 35 cSt to about 500 cSt at 100° C., wherein the processing aid comprises 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 comprises at least one primary amine, wherein the composition comprises at least one cure package or wherein the elastomeric composition has undergone at least one process to produce a cured composition and is substantially free of aromatic, naphthenic, paraffinic oils, or mixtures thereof.
A process to produce an elastomeric composition, the process comprising contacting at least one elastomer with a processing aid having a viscosity in the range of greater than 35 cSt to about 500 cSt at 100° C., wherein the processing aid comprises 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 comprises at least one primary amine, and a layered clay treated with a modifying agent, wherein the elastomeric composition comprises at least one cure package or wherein the elastomeric composition has undergone at least one process to produce a cured composition and is substantially free of aromatic, naphthenic, paraffinic oils, or mixtures thereof.
A process to produce an elastomeric composition, the process comprising contacting at least one elastomer with a processing aid having a viscosity in the range of greater than 35 cSt to about 500 cSt at 100° C. and a number average molecular weight in the range of 450 to 2,500, wherein the processing aid comprises 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 comprises at least one primary amine;
- and the composition is substantially free of aromatic, naphthenic, paraffinic oils, or mixtures thereof.
