Benefits of technology

[0013] The present invention is also directed to a golf ball comprising a soft, high specific gravity layer. Preferably, this layer also has a low moisture vapor transmission rate to d

Problems solved by technology

A known drawback of polybutadiene cores cross-linked with peroxide and/or zinc diacrylate is that this material is adversely affected by moisture.
Water moisture vapor reduces the resiliency of the cores and degrades its properties.
However,

Embodiment Construction

[0019] As shown generally in FIGS. 1 and 2, where like numbers designate like parts, reference number 10 broadly designates a golf ball in accordance to the present invention. Golf ball 10 preferably has a solid core 12, an intermediate layer 14 and a cover 16. Solid core 12 may comprise a single spherical element, or it may comprise a core spherical element with one or more intermediate layers surrounding the spherical element. Solid core 12 can be made from any suitable core materials including thermoset plastics, such as natural rubber, polybutadiene (PBD), polyisoprene, styrene-butadiene or styrene-propylene-diene rubber, and thermoplastics such as ionomer resins, polyamides, polyesters, or a thermoplastic elastomer. Suitable thermoplastic elastomers include Pebax®, which is believed to comprise polyether amide copolymers, Hytrel®, which is believed to comprise polyether ester copolymers, thermoplastic urethane, and Kraton®, which is believed to comprise styrenic block copolymer...

Abstract

A golf ball with at least one moisture vapor barrier layer is disclosed. In accordance to one aspect of the invention, the moisture vapor barrier layer may comprise a polysulfide rubber Polysulfide rubber may be applied to the golf ball in a liquid form curable at an elevated temperature or at room temperature. The liquid form may be mixed from two or more components prior to being applied to the ball. The liquid form may have water mixed therein before being applied to the ball. Alternatively, the liquid form may be applied to the ball without any additional mixing.

Description

STATEMENT OF RELATED PATENT APPLICATION [0001] This patent application is a continuation of co-pending U.S. application Ser. No. 10 / 759,494, filed on Jan. 16, 2004, which is a continuation of U.S. application Ser. No. 10 / 103,413, filed on Mar. 21, 2002, now abandoned, which is a continuation-in-part of U.S. application Ser. No. 09 / 973,342, filed on Oct. 9, 2001, now U.S. Pat. No. 6,632,147. These parent applications are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION [0002] The present invention relates to a novel structure for a golf ball, and more particularly to a golf ball with a moisture vapor barrier layer. BACKGROUND OF THE INVENTION [0003] Solid core golf balls are well known in the art. Typically, the core is made from polybutadiene rubber material, which provides the primary source of resiliency for the golf ball. U.S. Pat. Nos. 3,241,834 and 3,313,545 disclose the early work in polybutadiene chemistry. It is also known in the art that increasing ...
