    Abstract: A golf ball includes a thermoplastic HNP inner core layer having a center hardness less than the surface hardness to define a positive hardness gradient. An outer core layer is disposed about the inner core and is formed from a thermoset rubber composition. The core layer has an inner surface hardness less than the outer surface hardness to define a positive hardness gradient. Inner and outer cover layers are disposed about the outer core layer. The HNP composition includes an acid copolymer of ethylene and an α,β-unsaturated carboxylic acid; a non-acid polymer comprising polyolefins, polyamides, polyesters, polyethers, polyurethanes, metallocene-catalyzed polymers, single-site catalyst polymerized polymers, ethylene propylene rubber, ethylene propylene diene rubber, styrenic block copolymer rubbers, alkyl acrylate rubbers, or functionalized derivatives thereof; an organic acid or salt thereof; and a cation source in an amount sufficient to neutralize at least about 80% of the acid groups.

    Abstract: Golf balls having a core comprising a polyalkenamer rubber composition are provided. 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 and provides the ball with a comfortable and soft feel. In one version, a solid, single core having an outer surface and geometric center is provided, wherein the outer surface has a hardness greater than the hardness of the geometric center to define a positive hardness gradient of at least 10 Shore C. In a second version, a dual-core having an inner core and surrounding outer core layer is provided. The inner core has a positive hardness gradient, while the outer core has a zero; negative; or positive hardness gradient.
