    Abstract: Golf balls having a core comprising a polyalkenamer rubber composition are provided. The rubber composition may further include other rubbers such as, for example, polybutadiene, polyisoprene, ethylene propylene rubber, ethylene propylene diene rubber, and styrene-butadiene rubber. The rubber composition helps improve resiliency of the core and provides the ball with a comfortable and soft feel. In one version, a solid, single core having an outer surface and geometric center is provided, wherein the outer surface has a hardness greater than the hardness of the geometric center to define a positive hardness gradient of at least 10 Shore C. In a second version, a dual-core having an inner core and surrounding outer core layer is provided. The inner core has a positive hardness gradient, while the outer core has a zero; negative; or positive hardness gradient.

    Abstract: The invention is directed to a method of making a neutralized non-ionomeric polymer composition (NNIPC) suitable for use in a golf ball component comprising the steps of: providing a non-acid copolymer composition (NACC); soaking the NACC in an organic acid to form a soaked non-acid copolymer composition (SNACC); providing a cation source in an amount sufficient to neutralize at least a portion of the organic acid; and melt processing the SNACC and cation source to form the NNIPC. The invention also relates to a method of making a golf ball incorporating the NNIPC made according to the inventive method and to the resulting golf ball.

    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.

    Abstract: A golf ball includes a unitary core having an outer surface, a geometric center, and a soft transition region adjacent to the outer surface, and is formed from a substantially homogenous composition. The ball further includes an outer cover layer. The soft transition region has a thickness of up to 4 mm, has about 8 to 20 percent trans-polybutadiene isomer, and has a negative hardness gradient of up to 15 Shore C. The core has an overall negative hardness gradient of up to 20 Shore C and has a gradient quotient, GQ, defined by the equation: G + T 10 × COR ≤ 7 where G is the overall negative hardness gradient in Shore C, T is the percent of trans-polybutadiene isomer at the core outer surface, and COR is the coefficient of restitution measured at an incoming velocity of 125 ft/s.
