摘要：A golf ball comprising a core comprising a center and an outer core layersurrounding the center, the center having a compression of less than about 65 and a firstspecific gravity; the outer core layer having a hardness of at least 80 Shore C and asecond specific gravity greater than or equal to the first; and a cover disposed about theouter core layer; wherein at least one of the center or the outer core layer is formedfrom a fully-neutralized thermoplastic copolymer of ethylene and an α,β-unsaturatedcarboxylic acid, the acid being 100% neutralized by a salt of an organic acid, a cationsource, or a suitable base of the organic acid; and wherein the center has a hardness lessthan a hardness of the outer core layer.
