摘要： A method for producing an alkoxysilyl group-containing conjugated diolefin (co)polymer rubber by polymerizing a conjugated diolefin or a conjugated diolefin and an aromatic vinyl compound in a hydrocarbon solvent by anionic polymerization using as an initiator at least one metal compound selected from an organic alkali metal compound and an organic alkali earth metal compound, and then allowing an alkoxysilane-based compound to react, wherein after the alkoxysilane-based compound has been allowed to react, an alkaline compound is added at the time of desolvation, and treatment is conducted at a pH of 8 to 12.

摘要： The present invention provides a rubber composition that provides excellent vibration-isolating properties, a vibration isolating rubber formed from the rubber composition and a vibration-isolating mount. The rubber composition contains 5 to 40 parts by weight of a styrene-butadiene-based copolymer rubber, having a weight-average molecular weight of 200,000 or less and a glass transition temperature of −35° C. or higher; and 95 to 60 parts by weight of a diolefin-based rubber, having a weight-average molecular weight exceeding 200,000 and a glass transition temperature of −20° C. or lower; where the weight are based on 100 parts by weight of the total amount of both. A vibration-isolating rubber comprising this composition has a performance relationship between a dynamic-to-static modulus ration (Kd/Ks), which is a ratio of a dynamic spring constant (Kd) to a static spring constant (Ks), and a loss factor (tan &dgr;), as shown by the equation (1): Kd/Ks≦20 tan &dgr;−1.8 (1). This vibration-isolating rubber is used for a vibration-isolating mount.
