PROBLEM TO BE SOLVED: To obtain the subject composition having decreased temperature dependency of elastic modulus, enabling free setting of the attenuation at need and useful for a vibration isolation apparatus, etc., by adding a specific copolymer to a diene rubber. SOLUTION: This composition contains (A) 100 pts.wt. of a diene rubber, (B) >5 and <=50 pts.wt. of a thermoplastic elastomer copolymer containing styrene block and (C) 5-60 pts.wt. of a resin. Preferably, the component A is natural rubber, isoprene rubber, etc., the component B is a styrene-butadiene- styrene copolymer elastomer, etc., and the component C is a coumarone-indene resin having a softening point of >=100 deg.C, etc. |
