Core composition for golf ball

Abstract

A golf ball construction is provided having a solid core composition of a rubber having between 0.05 to 0.50 percent by weight of an additive selected from the group of titanium, tungsten, and combinations thereof, the additives providing an improved core composition having increased durability.

That which is claimed is:  
     
         1 . A golf ball core comprising: 
 an elastomeric core, and,    0.05 to 0.50 percent by weight of a particulate additive selected from the group consisting of titanium, tungsten, and combinations thereof.    
     
     
         2 . The core according to  claim 1  wherein the particulate additive is present in an amount of between about 0.05 to about 0.20 percent by weight.  
     
     
         3 . The core according to  claim 1  wherein the particulate additive is present in an amount of about 0.13 percent by weight.  
     
     
         4 . A golf ball comprising: 
 an outer cover; and,    a core, the core having at least one elastomer and a particulate additive of 0.05 to 0.50 percent by weight, the additive selected from the group consisting of titanium, tungsten, and mixtures thereof.    
     
     
         5 . A golf ball core composition comprising: 
 an elastomer of polybutadiene; and,    about 0.05 to about 0.50 percent by weight of a titanium metal, said titanium metal having an average particle size of between about 8 to about 10 microns.    
     
     
         6 . The golf ball core composition according to  claim 5  wherein said titanium is in the form of a platelet.  
     
     
         7 . The golf ball according to  claim 4  wherein said particulate additive is titanium and has an average particle size of between about 8 to about 10 microns.  
     
     
         8 . The golf ball core composition according to  claim 1  wherein said particulate additive is a mixture of a titanium metal and a tungsten metal.
