  A rubber vibration isolator lowered in the dynamic-to-static modulus ratio and improved in the durability is obtained by blending a natural rubber and/or a synthetic rubber with a filler and a dinitrodiamine compound represented by the formula of wherein X is a divalent aliphatic, alicyclic or aromatic group which may contain halogen or oxygen in the group, R1 is hydrogen, an aliphatic group, an alicyclic group or an aromatic group, with the proviso that two nitrogen atoms linking through X may further link through R1 when both X and R1 are the aliphatic groups, and R2 and R3 independently of one another are each hydrogen or an alkyl of 1 to 12 carbon atoms, with the proviso that R2 and R3 may conjointly form a ring.

  Rubber filled with an inorganic whity filler such as white carbon is improved in its vulcanized rubber properties such as tensile strength, tear strength and heat build-up resistance by incorporating thereto a dinitrodiamine compound represented by the formula of wherein X is a divalent aliphatic, alicyclic or aromatic group which may contain halogen or oxygen in the group, R¹ is hydrogen, an aliphatic group, an alicyclic group or an aromatic group, with the proviso that two nitrogen atoms linking through X may further link through R¹ when both X and R¹ are the aliphatic groups, and R² and R³ independently of one another are each hydrogen or an alkyl of 1 to 12 carbon atoms, with the proviso that R² and R³ may conjointly form a ring. The dinitrodiamine compound acts as a coupling agent for the rubber and the inorganic whity filler.
