Abstract:
1. A method of making a golf ball comprising: providing a core, optionally forming at least one intermediate layer about the core, forming a cover layer about the core or the at least one intermediate layer, wherein at least one of the core, the at least one intermediate layer, and the cover comprises at least one of an ionomer and an acid copolymer, is treated with an organometallic composition, and forms a treated golf ball component having at least one treated region wherein the at least one treated region comprises a reaction product of the organometallic composition and the at least one ionomer and/or acid copolymer; the at least one treated region having an internal neutralization gradient; or at least two treated regions, in tandem, having an external neutralization gradient; or the at least one treated region and an untreated region, in tandem, have an external neutralization gradient; and (a) where the treated golf ball component comprises a center, the treated region is formed before forming any of the intermediate layer and cover layer about the center; and (b) where the treated golf ball component is a golf ball layer comprising at least one of an outer core layer, an intermediate layer, an inner cover layer and an outer cover layer,
