Golf ball compositions
Disclosed herein are heterogeneous golf ball compositions comprising a thermosetting polymer matrix and discrete particles of thermoplastic polymer dispersed within the matrix.
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 at least 500 discrete particles of a thermoplastic polymer composition dispersed within the matrix, the thermoplastic composition having a melting point above the curing temperature of the thermosetting composition,
wherein the difference in the specific gravity of the thermosetting polymer composition and the specific gravity of the thermoplastic composition is at least 0.13 g/cm 3 .
2. The golf ball of claim 1 , wherein the difference in the specific gravity of the thermosetting polymer composition and the specific gravity of the thermoplastic composition is at least 0.20 g/cm 3 .
3. The golf ball of claim 1 , wherein the particles have a maximum particle size of 0.841 mm.
4. The golf ball of claim 1 , wherein the particles have a maximum particle size of 0.595 mm.
5. The golf ball of claim 1 , wherein the golf ball comprises a core and a cover, and wherein the cover comprises the layer formed from the heterogeneous composition.
6. The golf ball of claim 1 , wherein the golf ball comprises a core, a cover, and an intermediate layer disposed between the core and the cover, wherein the intermediate layer is formed from the heterogeneous composition.
