    Abstract: A golf ball includes a core and a three-layer cover disposed about the core. The cover includes a thermoplastic inner cover layer having a hardness of about 66 to 90 Shore C; an outer cover layer formed from a polyurethane, a polyurea, or a hybrid thereof, and an intermediate cover layer disposed between the inner and outer cover layers. The outer cover layer has a hardness of about 52 to 85 Shore C. The intermediate cover layer has a hardness of about 74 to 100 Shore C and greater than the inner cover layer hardness and the outer cover layer hardness. The thermoplastic inner cover comprises a highly-neutralized ionomer comprising a copolymer of ethylene and an α,β-unsaturated carboxylic acid, an organic acid or salt thereof, and sufficient cation source to neutralize the acid groups of the copolymer by about 100%.

    Abstract: Casing compositions including carboxyl groups, cover compositions including nucleophile groups and an adhesion promoter capable of crosslinking carboxyl and nucleophile groups, and golf balls made from such compositions that have crosslinks between carboxyl groups in the casing composition and nucleophile groups in the cover composition. The nucleophile groups may be hydroxyl groups, amino groups, or other types of nucleophile groups. The adhesion promoter may be a polyaziridine. An acid catalyst may be used to facilitate the reaction between the nucleophile groups in the cover composition and the adhesion promoter. The type and concentration of the components in the casing and cover compositions, including the adhesion promoter, affect the adhesion between golf balls having components made from such compositions and, thus, can be used to produce a golf ball having increased durability.

    Abstract: Casing compositions including carboxylic acid groups, cover compositions including an adhesion promoter with functional groups that crosslink with carboxylic acid groups, and golf balls made from such compositions that have crosslinks between functional groups of the cover compositions and the carboxylic acid groups. The type and concentration of the components in the casing and cover compositions, including the adhesion promoter, affect the adhesion between golf balls having components made from such compositions and, thus, can be used to produce a golf ball having increased durability. Additionally, methods of crosslinking casing and cover layers made from such casing and cover compositions to increase interlayer adhesion are disclosed.
