USE OF NUCLEATING AGENTS TO INCREASE THE FLEXURAL MODULUS OF IONOMERS
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.
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.
