Abstract

Disclosed herein are heterogeneous golf ball compositions comprising a thermoplastic matrix and discrete particles of crosslinked polymer dispersed within the matrix.

Claims (8)

1. A golf ball comprising an innermost core layer formed from a heterogeneous composition comprising a thermoplastic matrix and discrete particles dispersed within the matrix, wherein the discrete particles are formed from a crosslinked rubber composition having a Shore D hardness of 65 or greater, and wherein each of the discrete particles present in the composition has a particle size of from 0.030 mm to 2.38 mm, and wherein the discrete particles are present in the heterogeneous composition in an amount of 60 wt % or greater, based on the total weight of the heterogeneous composition.

2. A golf ball comprising an innermost core layer formed from a heterogeneous composition comprising a thermoplastic matrix and discrete particles dispersed within the matrix, wherein the discrete particles are formed from a crosslinked rubber composition comprising a peroxide initiator and 50 phr or greater of a coagent, and wherein each of the discrete particles present in the composition has a particle size of from 0.030 mm to 2.38 mm, and wherein the discrete particles are present in the heterogeneous composition in an amount of 60 wt % or greater, based on the total weight of the heterogeneous composition.

3. The golf ball of claim 2 , wherein the coagent is present in the crosslinked rubber composition in an amount of 75 phr or greater.

4. The golf ball of claim 3 , wherein the coagent is a non-metal coagent selected from unsaturated vinyl compounds, polyfunctional monomers, maleimides, and combinations of two or more thereof.

5. The golf ball of claim 2 , wherein the crosslinked rubber composition has a Shore D hardness of 65 or greater.

6. The golf ball of claim 2 , wherein the crosslinked rubber composition has a Shore D hardness of 70 or greater.

7. The golf ball of claim 2 , wherein the crosslinked rubber composition has a Shore D hardness of 80 or greater.

8. The golf ball of claim 2 , wherein the crosslinked rubber composition has a Shore D hardness of 90 or greater.
