    Abstract: A golf ball includes an inner core layer formed from a thermoset rubber composition. The inner core layer has a first outer surface Shore D hardness and an outer diameter of about 0.8 to 1.40 inches. A thermoplastic outer core layer is formed around the inner core layer, has a second outer surface Shore D hardness, and is formed from a copolymer of ethylene and an α,β-unsaturated carboxylic acid, a magnesium salt of oleic acid, and sufficient cation source to fully-neutralize the acid groups of the copolymer. The golf ball includes an inner cover layer and an outer cover layer. The first outer surface Shore D hardness is greater than the second outer surface Shore D hardness and the outer core layer has a thickness of about 0.01 inches to 0.05 inches.

    Abstract: A golf ball includes a ‘dual core’ formed from an inner core layer and an outer core layer. The inner core has an outer surface and a center and is typically formed from a substantially-homogenous rubber composition such that the center of the core has a hardness of about 72 Shore C to about 78 Shore C and a trans content of about 5% to 9%, and the outer surface of the inner core has a trans content of about 5% to 9%. The trans content of the outer surface and the center of the inner core are preferably within 2% of each other and, more preferably are substantially the same to define a zero trans gradient along a radius of the inner core.

    Abstract: A golf ball comprising a core and a cover layer having a cover inner surface and a cover outer surface that treated with and comprises a fatty acid and/or fatty acid salt composition and has a hardness α, the cover inner surface not being treated with and not comprising the fatty acid and/or fatty acid salt composition and having a hardness β. Hardness α is greater than hardness β. The cover layer may alternatively comprise an untreated cover region and a treated cover region that extends inward from the cover outer surface a depth of about 1% or greater of a distance between the cover outer surface and the cover inner surface. Alternatively, the treated cover region may extend inward from the cover outer surface a predetermined depth DCTr while the untreated cover region is disposed between the cover inner surface and the treated cover region a predetermined depth DCUTr.
