    Abstract: A golf ball comprising a core and a cover layer having a cover inner surface and a cover outer surface that treated with and comprises a fatty acid and/or fatty acid salt composition and has a hardness α, the cover inner surface not being treated with and not comprising the fatty acid and/or fatty acid salt composition and having a hardness β. Hardness α is greater than hardness β. The cover layer may alternatively comprise an untreated cover region and a treated cover region that extends inward from the cover outer surface a depth of about 1% or greater of a distance between the cover outer surface and the cover inner surface. Alternatively, the treated cover region may extend inward from the cover outer surface a predetermined depth DCTr while the untreated cover region is disposed between the cover inner surface and the treated cover region a predetermined depth DCUTr.

    Abstract: A golf ball is formed including a core and a cover. The cover includes a thermoplastic inner cover layer and having a hardness between 55 and 60 Shore D, an outer cover layer having a hardness between 55 and 60 Shore D, and a non-ionomeric thermosetting polyurethane or polyurea intermediate cover layer disposed between the inner and outer cover layers. The intermediate cover layer has a hardness greater than the inner cover layer hardness and the outer cover layer hardness. The inner cover is formed from a partially- or fully-neutralized ionomer and the outer cover layer is formed from a polyurethane, a polyurea, or a urethane-urea blend.

    Abstract: Methods for making golf balls having a cover made from a polyurea composition are provided. The golf balls include a rubber core and intermediate layer made from an olefin-based ionomer composition. The methods for making the polyurea composition involve preparing an amine-terminated first polymer by reacting isocyanate compound A with a stoichiometric excess of polyamine. The first prepolymer is reacted with a stoichiometric excess of isocyanate compound B to form an isocyanate-terminated second prepolymer. The second prepolymer is then reacted with a chain extender.

    Abstract: The invention is directed to a golf ball comprising: a single layer core and a cover layer disposed about the single layer core; the single layer core being formed from a substantially homogenous formulation and comprising a geometric center and an outer surface wherein the outer surface has a hardness greater than a hardness of the geometric center; the single layer core further comprising: an inner core region disposed about the geometric center; an outer core region disposed about the inner core region and adjacent the outer surface; and a boundary disposed between the inner core region and the outer core region at about 12 mm or less from the outer surface; wherein the boundary has a hardness that is greater than the hardness of the geometric center and greater than the hardness of the outer surface. In another embodiment, the boundary has a hardness that is greater than the hardness of the geometric center and less than the hardness of the outer surface.
