    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: Low compression multi-piece golf balls having a solid core comprising at least one layer made of a plasticized thermoplastic composition are provided. Preferably, the ball has a compression of less than 60 and more preferably less than 50. The ball includes a cover in addition to the core sub-assembly. For example, two-piece and three-piece golf balls may be made. The plasticized thermoplastic composition preferably comprises: a) ethylene acid copolymer, b) plasticizer, and c) cation source. Preferably, a fatty acid ester such as butyl oleate is used as the plasticizer. In two-layered core constructions, the outer core layer is preferably formed from a thermoset composition such as polybutadiene rubber. The core layers may have different hardness levels. The core structure and resulting ball have relatively good resiliency at given compressions.

    Abstract: A golf ball includes a thermoplastic inner core and a thermoset outer core layer. The inner core has a surface hardness of about 40 to 80 Shore C and a center hardness of about 30 to 75 Shore C, the center hardness being less than the surface hardness to define a first positive hardness gradient. The cover includes an inner cover layer and an outer cover layer. The thermoplastic inner core comprises a highly-neutralized ionomer including an acid copolymer of ethylene and an α,β-unsaturated carboxylic acid; a plasticizer; an organic acid or salt thereof; and a cation source present in an amount sufficient to neutralize from about 70 to 100% of the acid groups present. The outer core layer includes a polybutadiene rubber and has a surface hardness greater than an interior hardness to define a positive hardness gradient of less than about 25 Shore C

    Abstract: The invention is directed to a method of making a neutralized polymer composition (“NPC”) suitable for a golf ball component comprising the steps of: providing an acid copolymer composition; soaking the acid copolymer composition in an organic acid to form a soaked polymeric composition wherein substantially all of the organic acid is absorbed within the acid copolymer composition; providing a cation source in an amount sufficient to neutralize the acid copolymer and organic acid; and melt processing the soaked polymeric composition and cation source to form a neutralized polymer composition. The invention also relates to a method of making a golf ball incorporating the NPC made according to the inventive method and to the resulting golf ball.
