Abstract: Compositions including a hardness agent, a water releasing agent, and a complexing agent and golf ball cores made from such compositions having a tailored hardness gradient are disclosed. The type and concentration of the components in the composition affect the hardness, hardness gradient, and compression of cores made from the composition and, thus, can be used to produce a golf ball having desirable performance characteristics.

Abstract: The present disclosure provides methods of reducing center shifting of golf ball components, which, in turn, improves concentricity of the resulting golf balls. The methods include extruding a golf ball component material through an extruder to form an extrudate having a first temperature, cutting the extrudate at a second temperature to form a component prep, and molding the component prep into the golf ball component. The preps formed by the methods of the present disclosure include surfaces having reduced or no concavity.

Abstract: Compositions including a water releasing agent and golf ball cores made from such compositions having a high hardness gradient are disclosed. The type and concentration of the components in the composition, including the water releasing agent, affect the hardness and hardness gradient of cores made from the composition and, thus, can be used to produce a golf ball having desirable performance characteristics. Cores made from the composition may be cured using infrared radiation to further increase the hardness and hardness gradient of such cores. Cores cured using infrared radiation may have a center and a skin with hardness greater than the hardness of the center to produce a high hardness gradient.

Abstract: Golf balls having cores with increased hardness gradients are provided. The cores have an increased “positive” hardness gradient (or a “hard-to-soft” hardness) where the outer surface of the core is harder than the center. The increased positive hardness gradient can be achieved by introducing a water-releasing agent into the core rubber formulation during the curing process. The resulting golf balls have reduced spin and sufficient impact durability.

Abstract: Color-shifting formulations and golf balls including color-shifting formulations where the color-shifting formulations produce a golf ball with a color appearance that differs from the color appearance of the subassembly and the color appearance of the color-shifting formulation and also exhibits an angular color shift.
