    摘要： Multi-layer golf balls having a thin, relatively hard outer core layer surrounding a large, relatively soft inner core layer are provided. The inner core layer generally has a diameter of from 1.5 inches to 1.55 inches. The outer core layer generally has an outer diameter of from 1.6 inches to 1.64 inches. A cover is provided to surround the outer core layer. A moisture barrier layer is optionally provided between the outer core layer and the cover.

    摘要： Multi-piece golf balls having a multi-layered solid core and multi-layered cover are provided. In one version, a five-piece ball is formed, wherein the inner cover layer is made of a thermoplastic composition such as a highly neutralized (HNP) composition. The outer cover layer is made of a composition comprising a polyurethane, polyurea, or copolymer or blend thereof. In a second version, a six-piece ball having inner and intermediate cover layers that also can be made of HNP compositions is produced. The five and six-piece balls also include multi-layered core structures with a center made of a thermoset rubber. The finished balls have high resiliency and rebounding properties.

    摘要： A golf ball has an inner core layer including a thermoplastic highly-neutralized ionomer and having a geometric center hardness less than a surface hardness to define a first positive hardness gradient. An outer core layer is formed about the inner core and includes a homogenous thermoset composition. The outer core has an interior hardness less than an outer surface hardness to define a second positive hardness gradient. An inner and outer cover layers are disposed about outer core layer. The first and second hardness gradients each have a slope and the slope of the second hardness gradient is less than the slope of the first hardness gradient such that a ratio of the first and second slopes is 0.8 to 0.85.

    摘要： A golf ball includes an inner core layer formed from a thermoplastic material. The inner core has a center hardness that is greater than the surface hardness to define a negative hardness gradient. An outer core layer is disposed about the inner core. The outer core has a surface hardness that is greater than the surface hardness of the inner core to define a positive hardness gradient. An inner cover layer and an outer core layer are formed over the outer core layer. The negative hardness gradient of the inner core is about −1 to −5 Shore C, the positive hardness gradient of the outer core layer is less than 25 Shore C, the surface hardness of the outer core layer is about 45 Shore D to about 70 Shore D, and the surface hardness of the inner core is about 20 Shore D to about 60 Shore D.
