摘要
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 ofwherein 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.
