摘要：A vibration-damping material with excellent workability consists of two metalplates and a vibration-damping layer of a thermoplastic resin interposed between thetwo metal plates, in which the vibration-damping layer of a thermoplastic resin consists ofa film as a middle layer and a polyolefin type resin (B) provided on both sides of the filmas an upper and lower layer, the film as the middle layer being composed of (1) at leastone resin (A) selected from the group consisting of polyolefin type resins and ionomerresins each having a modulus of elasticity in shear at 20°C of 3 x 10 to 1 x 10 dyne/cm, apercentage of elongation at 20°C of 50% or above and a peak temperature of dissipationfactor (tan 6) of -120°C to 80°C or (2) a resin mixture of the resin (A) and a syntheticrubber having a percentage of elongation at 20°C of 100% or above and a peak

temperature of dissipation factor (tan δ) of -120°C to 50°C, and the polyolefin type resin(B) having a modulus of elasticity in shear at 20°C larger than that of the resin (A), apercentage of elongation at 20°C of 10% or above, a peak temperature of dissipationfactor (tan δ) of -40°C to 180°C and a bonding strength toward the metal plates at 20°C

and 180°C-peeling of 3 kg/cm or above.
