Abstract:
A hollow golf ball center defined by an intermediate layer including a thermoplastic ionomer resin neutralized at least about 40% with a metal cation is filled with an alcohol having up to three carbon atoms or an aqueous alcohol solution to create a hardness gradient in the intermediate layer. The alcohol or aqueous alcohol solution may be left in the center, removed from the center leaving the center hollow, or replaced by another material.
