Abstract

Disclosed herein are heterogeneous golf ball compositions comprising a matrix formed from a thermosetting polymer composition and discrete particles of crosslinked rubber dispersed within the matrix.

Claims (9)

1. A golf ball comprising a layer formed from a heterogeneous composition, the heterogeneous composition comprising:

a matrix formed from a thermosetting polymer composition, 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 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 a layer formed from a heterogeneous composition, the heterogeneous composition comprising:

a matrix formed from a thermosetting polymer composition, 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 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, wherein the crosslinked rubber composition has a Shore D hardness of 65 or greater.

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

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

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