An object of the present invention is to provide a golf ball having excellent resilience performance. The present invention provides a golf ball comprising a constituent member, wherein at least a part of the constituent member is formed from a rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, (c) a crosslinking initiator, and (d) an organic sulfur compound, wherein (d) the organic sulfur compound contains at least one member selected from the group consisting of a thiophenol having a halogenated sulfanyl group, a metal salt of a thiophenol having a halogenated sulfanyl group, and a diphenyl disulfide having a halogenated sulfanyl group.

An object of the present invention is to provide a golf ball traveling a great flight distance and having a good shot feeling and durability on driver shots. The present invention provides a golf ball comprising a core, at least one intermediate layer covering the core and a cover covering the intermediate layer, wherein the core is formed from a core rubber composition containing (a) a base rubber containing a polybutadiene, (b) an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or a metal salt thereof as a co-crosslinking agent, (c) a crosslinking initiator, and (d) a terpene-based resin, and a material hardness (Hm) of the intermediate layer and a material hardness (Hc) of the cover satisfy an equation of Hm≤Hc.

The present disclosure provides a wireless signal transmitting ball to be used in practice or gameplay of a sport and/or other entertainment activities. The ball of the disclosure comprises a microprocessor unit configured to record, process, and transmit data to a paired device. Further disclosed is a method of actuating the ball between different modes. The ball could be used by players during practice to record data about their performance. The ball could also be used by players or game officials or referees to keep score, adjudicate and decide the gameplay. For example, the information about location of the ball could be used to track balls that could potentially be lost. Additionally, data about spin, trajectory, speed, force applied and the like could be used by players or broadcasters for gaining insights to add to viewing pleasure.

Golf balls having a single or dual-layered solid core are provided. In one embodiment, the golf ball has dimensions and properties that do not conform to the rules of the United States Golf Association (USGA). For example, the ball weight; ball size; ball spherical symmetry; ball initial velocity; and/or ball overall distance may fall outside of the USGA standards. The dual-layered core can have an inner core comprising a thermoplastic composition and surrounding outer core comprising a thermoset composition. In another embodiment, the dual-layered core has an inner core comprising a thermoplastic composition and outer core comprising a thermoset composition. The thermoplastic composition preferably comprises an ethylene acid copolymer ionomer and plasticizer. The thermoset composition preferably comprises polybutadiene rubber. The ball further includes a cover of at least one layer.

This disclosure relates to a ball comprising a core and a porous structure encompassing the core. The porous structure comprises a plurality of perforations in its outer surface, which are connected with a plurality of hollow confined spaces within the porous structure allowing a liquid to be at least partly absorbed by the hollow confined spaces upon contact of the ball with the liquid. A shell with shell perforations encompasses the porous structure. The ball comprises control means for controlling the absorption of liquid by the ball and the release of absorbed liquid from the ball.

The use of a low molecular weight farnesene, poly(farnesene), and farnesene copolymer in a golf ball is disclosed herein. In a core, low molecular weight farnesene, poly(farnesene) or farnesene copolymer is blended with 1,4 polybutadiene or a polyalkenamer. In a mantle layer, low molecular weight farnesene, poly(farnesene), and/or farnesene copolymer can be blended with non- or partially neutralized copolymeric or terpolymeric ionomer(s). In a cover, low molecular weight farnesene, poly(farnesene), and farnesene copolymer can be blended with highly neutralized ionomer.
