Abstract:
A high performance golf ball includes a resin inner core, a rubber outer core, and a cover. The resin inner core is made of a blend of highly neutralized polymers and a low flexural modulus ionomer, and may include a blend of different highly neutralized polymers. The inner core has a specified relationship of coefficients of restitution of the various layers of the ball. The cover is a single layer ionomer cover, and may be made from a blend of different grades of the ionomer. The ball as a whole has properties to maximize performance and aesthetic properties, such as backspin off the irons, feel, and sound.
