GOLF BALL COMPOSITIONS
Disclosed herein are heterogeneous golf ball compositions comprising discrete particles of crosslinked rubber dispersed within an acid copolymer-based matrix. Also disclosed herein are golf ball compositions comprising a silicone ionomer.
1 . A golf ball comprising a layer formed from a composition comprising at least one silicone ionomer.
2 . The golf ball of claim 1 , wherein the composition is a thermoplastic composition additionally comprising an E/X/Y-type ionomer of ethylene (E), an α,β-unsaturated carboxylic acid (X), and optionally a softening comonomer (Y).
3 . The golf ball of claim 1 , wherein the composition is a thermoplastic composition additionally comprising a thermoplastic polyurethane.
4 . The golf ball of claim 1 , wherein the composition is a thermoplastic composition additionally comprising a polyester.
5 . The golf ball of claim 1 , wherein the composition is a thermoplastic composition additionally comprising a polyamide.
6 . The golf ball of claim 1 , wherein the composition is a thermoset composition additionally comprising a thermosetting polyurethane.
7 . The golf ball of claim 1 , wherein the composition is a thermoset composition additionally comprising a diene rubber.
8 . A golf ball comprising a core and an outer cover layer, wherein the outer cover layer has a thickness of less than 0.050 inches, a material hardness of from 20 Shore D to 60 Shore D, and is formed from a composition comprising at least one silicone ionomer.
9 . A golf ball comprising a core, an outer cover layer, and an intermediate layer disposed between the core and the outer cover layer, wherein the intermediate layer has a thickness of from 0.030 inches to 0.150 inches, a material hardness of from 10 Shore D to 55 Shore D, and is formed from a composition comprising at least one silicone ionomer.
