    Abstract: A golf ball comprising a core comprising at least one layer that consists of a mixture of a plurality of synthetic flocks and a thermoset rubber composition. The plurality of synthetic flocks has a melting temperature that is greater than a mixing temperature at which the mixture is formed. Additionally, the at least one layer comprises an outer surface having an outer surface hardness of about 80 Shore C or greater and the outer surface hardness is greater than a center hardness of a geometric center of the core by at least 20 Shore C. A cover having at least one layer is disposed about the core. The synthetic flocks may be included in the mixture in an amount of from about 0.5 parts to about 15 parts of the total mixture. Examples of suitable synthetic flocks include nylon, polyester, polypropylene, aramid, or acrylic flocks, or combinations thereof.

    Abstract: A golf ball includes an inner core layer including a thermoplastic highly-neutralized ionomer formed from a copolymer of ethylene and an α,β-unsaturated carboxylic acid, an organic acid or salt thereof, and sufficient cation source to neutralize the acid groups of the copolymer by 80% or greater. The inner core has a geometric center hardness and a surface hardness to define a first hardness gradient having a first slope, S1. An outer core layer is disposed about the inner core and is formed from a homogenous thermoset composition. The outer core layer has an interior hardness and an outer surface hardness to define a second hardness gradient having a second slope, S2. An inner cover layer is disposed about outer core layer and an outer cover layer is disposed about the inner cover layer. A ratio of S2 to S1 is about 1.0 or greater.

    Abstract: A golf ball comprising a single layer core formed from a substantially homogenous formulation and comprising a geometric center and an outer surface; a hardness of the outer surface is greater than a hardness of the geometric center. An inner core region is disposed about the geometric center and has a first hardness that is less than those of the geometric center and the outer surface; an outer core region is adjacent the outer surface and has a second hardness that is greater than those of the geometric center and the outer surface; and an intermediate core region is disposed between the inner and outer core regions and extends radially from about 5 mm to about 15.75 mm from the geometric center and has at least a third hardness and a fourth hardness, each of which are related to the first hardness and the second hardness in various ways.
