    摘要: A golf ball comprising:

    a core comprising a high cis-1,4 content polybutadiene, 20 to 28 parts by weight of a co-crosslinking agent comprised primarily of a zinc salt of an unsaturated acrylate, 3 to 5 parts by weight of a metal oxide activator, an 0.8 to 1.5 parts per hundred resin of a free radical initiator;
    a mantle comprising a terpolymer consisting of 70 to 80% ethylene, 8 to 10.5% acrylic acid and 12 to 20% n-butyl acrylate;
    a cover having an inner cover and an outer cover;
    the inner cover layer comprises a blend of ionomers; and
    the outer layer comprising a thermoplastic polyurethane.
