    Abstract: A golf ball including an inner core having a first outer surface and a geometric center and being formed from a first substantially homogenous composition such that the inner core has a hardness of about 60 Shore C to about 90 Shore C; an outer core layer disposed about the inner core having a second outer surface and being formed from a second substantially homogenous composition such that the outer core layer has a hardness of about 60 Shore C to about 95 Shore C; and a cover layer disposed about the outer core layer. The geometric center and first and second outer surfaces each have a hardness, the hardness of the second outer surface being lower than the hardness of the geometric center to define a negative hardness gradient.

    Abstract: A golf ball includes a core and a three-layer cover disposed adjacent the core. The three-layer cover includes an inner cover, an intermediate cover, and an outer cover. The inner cover includes a non-ionomeric E/Y copolymer where E is an olefin and Y is a carboxylic acid. The inner cover has a hardness of about 45 to 68 Shore D. The outer cover includes a castable thermoset polyurethane and has a hardness of about 40 to 62 Shore D. The intermediate cover layer, disposed between the inner and outer cover layers, is formed from a polyamide composition, where the polyamide composition includes a transparent polyamide having a light transmission of about 50% or greater.

    Abstract: Multi-piece golf balls containing a core of at least one layer and cover of at least one layer are provided. At least one component is formed from a rubber composition comprising: i) about 10 to about 65 weight percent of a cycloalkene rubber having a trans-content of about 55% or greater and a melting point of 30° C. or greater; ii) about 30 to about 80 weight percent of an ionomeric resin; and 3) about 5 to about 40 weight percent of a polyamide. The rubber composition may further include other thermoplastic and thermosetting materials such as, for example, polybutadiene, polyisoprene, ethylene propylene rubber, ethylene propylene diene rubber, and styrene-butadiene rubber. The rubber composition helps improve resiliency, durability, scuff-resistance, and feel of the ball.
