Abstract

A golf ball including a core formed from a halogenated thiophenol and having a diameter of 1.30 inches to 1.40 inches, a compression of 45 or less; and a coefficient of restitution of 0.780 or greater at 125 ft/s; and a cover having a thickness of 0.14 inches to 0.16 inches and being formed from a composition comprising a Na-ionomer and a Li-ionomer blend having a Shore D hardness of 60 to 70; wherein a combination of the core and the cover results in the golf ball having a compression of 85 to 95, and a coefficient of restitution of 0.815 to 0.825 at about 125 ft/s.

       2 . The golf ball of  claim 1 , wherein the core diameter is 1.35 inches to 1.40 inches.  
   
   
       3 . The golf ball of  claim 1 , wherein the combination of the core and the cover results in the golf ball having a coefficient of restitution of 0.750 of greater when measured at an incoming velocity of 160 ft/s.  
   
   
       4 . The golf ball of  claim 1 , wherein the coefficient of restitution of the core is 0.795 or greater when measured at an incoming velocity of 125 ft/s.  
   
   
       5 . The golf ball of  claim 1 , wherein the halogenated thiophenol is present in an amount from 0.01 pph to 5 pph.  
   
   
       6 . The golf ball of  claim 1 , wherein the Na-ionomer and Li-ionomer blend has a ratio of 10:90 to 90:10.  
   
   
       7 . A golf ball comprising: 
 a core comprising a halogenated thiophenol, and having a diameter of 1.40 inches or less, a compression of 60 or less; and a coefficient of restitution of 0.780 or greater when measured at an incoming velocity of 125 ft/s; and    a cover having a thickness of 0.101 inches to 0.25 inches and being formed from a composition comprising at least a first and second ionomer, the first ionomer being partially- or fully-neutralized by a first metal cation and the second ionomer being neutralized by a second metal cation different from the first;    wherein the combination of the core and the cover results in the golf ball having a coefficient of restitution of 0.760 of greater when measured at an incoming velocity of 160 ft/s.    
   
   
       8 . The golf ball of  claim 7 , wherein the cover further comprises partially- or fully-neutralized ionomers, metallocene-catalyzed polymers, single-site catalyzed polymers, polyesters, polyethers, balata, crosslinked diene rubbers, styrene block copolymers, polyurethanes, polyureas, polyurethane-ureas, polyurea-urethanes, or non-ionic fluoropolymers.  
   
   
       9 . The golf ball of  claim 7 , wherein the halogenated thiophenol is present in an amount of from 0.01 pph to 5 pph.  
   
   
       10 . The golf ball of  claim 7 , wherein the combination of the core and the cover results in the golf ball having a coefficient of restitution of 0.810 to 0.825 when measured at an incoming velocity of 125 ft/s.  
   
   
       11 . The golf ball of  claim 7 , wherein the first and second ionomers are blended in a ratio of 10:90 to 90:10.  
   
   
       12 . The golf ball of  claim 7 , wherein the core diameter is 1.30 inches to 1.40 inches.  
   
   
       13 . The golf ball of  claim 12 , wherein the core diameter is 1.35 inches to 1.40 inches.
