    摘要: The present invention provides a rubber composition having a high impact resilience, and improved processability and workability which may be used for the manufacture of a one-piece solid golf ball, the solid core of multi-layered solid golf balls or the solid centre of thread-wound golf balls. The rubber composition is characterized in that the rubber component is made from a mixture of:

    (1) 60 to 95 wt% of a polybutadiene containing at least more than 40% of cis-1,4-bonds and having a Mooney viscosity [ML₁₊₄(100°C)] of 50 to 70, obtained by using a lanthanum rare earth-based catalyst, nickel-based catalyst or cobalt-based catalyst, or a mixture thereof with another polybutadiene obtained by using a catalyst other than the above mentioned one, and
    (2) 5 to 40 wt% of a polyisoprene containing at least more than 90% of cis-1,4-bonds and a Mooney viscosity of 70 to 90.

    摘要: A golf ball which has an excellent ball velocity, flight distance and low-temperature durability, uses an ionomer resin of an ethylene-acrylic acid copolymer as the cover resin. The golf ball comprises a core and a cover covering the core, the cover having a total neutralization degree of 30 to 60%, of which at least 10% is neutralized with divalent metal ions, and being prepared by mixing specificethylene-acrylic copolymer type ionomer resins.
