Zusammenfassung:	To provide an elastomeric nanocomposite composition improved in the stability of the Mooney viscosity of the composition over time.SOLUTION: An elastomeric nanocomposite composition comprises at least one elastomer, at least one nanofiller, and an ionomer stabilizer in an amount of at least about 0.5 phr of the composition. The elastomer comprises units derived from isoolefins having 4 to 7 carbon atoms and at least one multiolefin. The nanofiller comprises a layered filler. The provision of the elastomeric nanocomposite composition improves the stability of the Mooney viscosity of the composition over time.SELECTED DRAWING: Figure 1 【課題】経時の組成物のムーニー粘度の安定性が改良されたエラストマーのナノ複合材料組成物を提供すること。【解決手段】少なくとも一種のエラストマー、少なくとも一種のナノ充填剤、及び組成物の少なくとも約0.5 phrの量のイオノマー安定剤を含み、そのエラストマーは４個から７個までの炭素原子を有するイソオレフィン及び少なくとも一種のマルチオレフィンから誘導された単位を含み、ナノ充填剤が層状充填剤からなるエラストマーのナノ複合材料組成物を提供することにより、経時の組成物のムーニー粘度の安定性が改良される。【選択図】図１
