Abstract:
1. A golf ball comprising: a core having a first outer surface; a cover; and an intermediate layer disposed between the core and the cover, the intermediate layer comprising a high melt flow non-ionic hydrophobic stiff fluoropolymer comprising a copolymer of tetrafluoroethylene and hexafluoropropylene having a melt viscosity of 10 KPoise or less at 230° C., a surface energy of less than about 75 dyne/cm wherein at least one of the first or second outer surfaces are treated with an functional silane such that a sufficient number of surface amine, hydroxyl, carboxylic acid, or epoxy groups are available for binding to an adjacent layer; and wherein the intermediate layer has a specific gravity of 1.3 to about 1.6 measured in the absence of a density-adjusting filler.
