NANOCOMPOSITE MOONEY VISCOSITY STABILITY

摘要

This invention relates to an elastomeric nanocomposite composition, the composition comprising at least one elastomer, at least one nanofiller, and an ionomer stabilizer in the amount of at least about 0.5 phr of the composition, the elastomer comprising units derived from isoolefins having from 4 to 7 carbon atoms and at least one multiolefin, and the nanofiller consisting of a layered filler, wherein the stabilizer is added to improve the stability of the Mooney viscosity of the composition over time.
