Abstract

The invention is directed to a golf ball comprising a core, a cover and optionally an intermediate layer disposed between the core and the cover, wherein at least one of the core, the intermediate layer and the cover comprises a moisture vapor barrier layer formed from a moisture vapor barrier composition comprising at least one diene rubber and at least one fluorinated silane treated filler. The filler is hydrophobically modified by fluorinated silane, a hydrophobizing material capable of rendering the surfaces of the silica particles suitably hydrophobic. This moisture vapor barrier composition, which may be incorporated in the golf ball prior to molding, protects the encased inner golf ball components from moisture penetration which damages the golf ball and deteriorates desired golf ball characteristics. Such a golf ball preserves and even enhances optimum golf ball properties and desired golf ball characteristics such as high spin, resilience and durability which may be negatively influenced or impacted by unintended changes in golf ball component compression, COR and hardness due to moisture invasion. The golf ball may comprise an untreated region and a treated outer surface, the treated outer surface having a moisture vapor transmission rate X and the untreated region having a moisture vapor transmission rate Y, the treated outer surface being treated with and comprising a moisture vapor barrier composition formed from at least one diene rubber and at least one fluorinated silane treated filler such that X<Y.

Claims

exact text as granted — not AI-modified
1 . A golf ball comprising:
 a core, a cover and optionally an intermediate layer disposed between the core and the cover,   wherein at least one of the core, the intermediate layer and the cover comprises a moisture vapor barrier layer formed from a moisture vapor barrier composition comprising at least one diene rubber and at least one fluorinated silane treated filler.   
     
     
         2 . The golf ball of  claim 1 , wherein the filler is selected from the group comprising silica, carbon black, graphite, nano graphite, carbon nanotubes and carbon nanoflakes. 
     
     
         3 . The golf ball of  claim 2 , wherein the silica is precipitated silica. 
     
     
         4 . The golf ball of  claim 2 , wherein the filler further comprises at least one of a non-fluorinated silane treated silica, fibers, flakes, and a sulfur-comprising organosilicon composition. 
     
     
         5 . The golf ball of  claim 1 , wherein the filler is present in an amount of from about 1 phr to about 40 phr. 
     
     
         6 . The golf ball of  claim 1 , wherein the diene rubber comprises high cis polybutadiene rubber that is is cobalt-catalyzed, nickel-catalyzed, lithium-catalyzed, or neodymium-catalyzed. 
     
     
         7 . The golf ball of  claim 1 , wherein the diene rubber comprises ethylene propylene diene monomer rubber. 
     
     
         8 . The golf ball of  claim 1 , wherein the diene rubber comprises a blend of high cis polybutadiene rubber and at least one different rubber selected from the group comprising natural rubber, balata, trans polyisoprene, styrene butadiene rubber, ethylene propylene rubber, ethylene propylene diene monomer rubber, butyl rubber, halo-butyl rubber, low-cis polybutadiene rubber, and trans polybutadiene rubber. 
     
     
         9 . The golf ball of  claim 8 , wherein the ratio of high cis polybutadiene rubber to the at least one different rubber is from about 9:1 to about 1:9. 
     
     
         10 . The golf ball of  claim 8 , wherein the ratio of high cis polybutadiene rubber to the at least one different rubber is from about 6:4 to about 4:6.
