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 (5)

1. A golf ball comprising a core, a cover layer, and optionally at least one intermediate layer disposed between the core and the cover layer, wherein at least one portion of the ball comprises an ionomer composition modified with a nucleating agent, and wherein the nucleating agent is selected from the group consisting of aluminum benzoate, sodium benzoate, potassium benzoate, sodium betanaphtholate, lithium benzoate, aluminum t-butylbenzoate, and combinations thereof.

2. The golf ball of claim 1 , wherein the ionomer composition is partially or fully neutralized with metal ions.

3. The golf ball of claim 2 , wherein the metal ions comprise Zn, Na, Li, K, Ca, Mg, Ni, Mn, Cu, Ti, Al , or a combination thereof.

4. The golf ball of claim 1 , wherein the nucleating agent is capable of increasing the flexural modulus of the ionomer composition.

5. The golf ball of claim 1 , wherein the ionomer composition comprises at least two ionomers.
