    摘要: A multi-layered core golf ball wherein each core layer comprises its own specific hardness gradient in addition to an overall specific hardness gradient from one core layer to the next. The inner core layer comprises a plurality of hardnesses of from about 50 Shore C to about 90 Shore C, a diameter of about 30 mm or lower, and a geometric center comprising a hardness greater than that of a first outer surface to define a negative hardness gradient of about 15 Shore C or greater. The outer core layer comprises a plurality of harnesses of from about 50 Shore C to about 95 Shore C, a thickness of about 10 mm or lower, and a second outer surface comprising a hardness greater than that of an inner surface to define a positive hardness gradient of about 20 Shore C or greater. A further outer core layer hardness, disposed in a region extending between about 10% and about 90% of the distance from the inner surface to the second outer surface, is greater than that of the inner and second outer surfaces. Also, the hardness of the second outer surface is similar to or less than that of the geometric center.

    摘要: Golf balls golf balls containing a core having at least two layers made from a polyalkenamer rubber composition are provided. At least one layer is made from a relatively low modulus polyalkenamer rubber composition and at least one layer is made from a relatively high modulus polyalkenamer rubber composition. The rubber composition may further include other rubbers such as, for example, polybutadiene, polyisoprene, ethylene propylene rubber, ethylene propylene diene rubber, and styrene-butadiene rubber. The rubber composition helps improve resiliency of the core. In one version, a dual-core having an inner core and surrounding outer core layer is provided. In another version, the golf ball contains a three-piece core having an intermediate core layer made of polybutadiene rubber.
