Abstract
Official abstract text for this publication.
Disclosed herein are heterogeneous golf ball compositions comprising a thermoplastic matrix and discrete particles of crosslinked polymer dispersed within the matrix.
First claim
Opening claim text (preview).
What is claimed is: 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.
