Abstract: A golf ball comprising a core, an outer cover layer, and, optionally, an intermediate layer disposed between the core and the outer cover layer is provided. The core, intermediate layer, or cover layer includes a composition formed from a base polymer blend, a crosslink initiator, and at least one additive. The outer cover layer may comprise a polyurethane or polyurea composition. The base polymer blend preferably includes two or more rubber materials. The additive has at least one C—O—B linkage, the carbon in the linkage being a secondary or tertiary carbon and is selected from the group consisting of boranes, borates, boronates, borinates, heterocylic compounds having at least one boron atom as a ring member, boron-containing organosulfides, salts of such additives, and metal salts, organometallic salts, and non-metal salts of boron complexes.

Abstract: A method of forming a water vapor barrier layer to a core of a golf ball is provided. The method includes placing the core of the golf ball into a vapor barrier composition, withdrawing the lifting device, and spinning and optionally oscillating the core within the composition for a time sufficient for the composition to form a layer on the core. The present invention also provides an apparatus that can be used to form a water vapor barrier layer.

Abstract: The present invention is directed to golf balls having at least one layer formed from a polyurea composition. The polyurea is formed by combining an aliphatic polyurea prepolymer, a diamine curative, and a cyclic carbonate diluent. Golf balls of the present invention include one-piece, two-piece, multi-layer, and wound golf balls. The composition may be present in any one or more of a core layer, a cover layer, or an intermediate layer.

Abstract: The present invention is directed to golf balls having at least one layer which comprises a polymer produced by a process wherein one or more monomers are contacted with a composition comprising the admixture or reaction product resulting from combining (A) a first olefin polymerization catalyst, (B) a second olefin polymerization catalyst capable of preparing polymers differing in chemical or physical properties from the polymer prepared by the first olefin polymerization catalyst under equivalent polymerization conditions, and (C) a chain shuttling agent. Golf balls of the present invention include one-piece, two-piece, and multi-layer golf balls. In two-piece and multi-layer golf balls of the present invention, the polymer may be present in a core layer, a cover layer, an intermediate layer (in the case of multi-layer balls), or a combination thereof.

Abstract: A golf ball comprising a core, a cover and at least on intermediate layer therebetween. The intermediate layer includes pigment which contributes to the color or appearance of the ball and the cover is at least partially transparent such that the intermediate layer is at least partially visible. The cover is also comprised of an optical enhancer.

Abstract: A method for inspecting golf balls is disclosed. The method comprises the steps of providing at least one sensor capable of obtaining images of the infrared radiation emitted from the ball, obtaining at least one image of the ball using the sensor after paint or a coating has been applied to the surface of the ball, and determining whether the liquid was applied evenly on the surface of the ball. Preferably, the image is obtained during the transient period when the solvent in the paint or coating is evaporating. A number of numerical analysis can be used to determine the evenness of the paint or coating.

Abstract: Polyurethane-based and polyurea-based compositions including modified amine curing agents for use in golf ball layers where modified amine curing agent of the invention allows control of the reaction rate by providing a composition with both primary and secondary amine linkages.
