Abstract

A golf ball composition having a copolymer with an acid content modified by a nucleating agent is described. The nucleating agent modifies the flexural modulus of the acid copolymer.

Claims

exact text as granted — not AI-modified
1 . A golf ball comprising a core, a cover layer, and an intermediate layer disposed between the core and the cover layer, wherein the intermediate layer is formed from an ionomer composition modified with a nucleating agent, and wherein the nucleating agent is a mineral nucleating agent. 
     
     
         2 . The golf ball of  claim 1 , wherein the mineral nucleating agent is selected from the group consisting of carbon black, silica, kaolin, talc, and combinations thereof. 
     
     
         3 . The golf ball of  claim 1 , wherein the ionomer composition is partially or fully neutralized with metal ions. 
     
     
         4 . The golf ball of  claim 3 , wherein the metal ions comprise Zn, Na, Li, K, Ca, Mg, Ni, Mn, Cu, Ti, Al, or a combination thereof. 
     
     
         5 . The golf ball of  claim 1 , wherein the nucleating agent is capable of increasing the flexural modulus of the ionomer composition. 
     
     
         6 . The golf ball of  claim 1 , wherein the ionomer composition comprises at least two ionomers.
