Abstract

A golf ball having a core and at least one layer disposed about the core is disclosed. The at least one layer is formed from a composition having multiple reactive and/or non-reactive ingredients. At least one of these ingredients is an isocyanate having a fused or bridge cyclic structure that is partially alicyclic and partially aromatic.

Claims

1. A golf ball comprising:

a core having a diameter of 1 inch or greater; and

at least one layer disposed about the core, wherein the layer has a thickness of from 0.005 inches to 0.1 inches and is formed from a polyurea composition, wherein the polyurea composition is formed from a composition comprising a (poly)amine having a fused or bridge cyclic structure that is partially alicyclic and partially aromatic, wherein the (poly)amine is selected from the group consisting of 2-amino-tetrahydronaphthalenes;

3-amino-tetrahydronaphthalenes;

2,3-diamino-tetrahydronaphthalenes;

2,4-diamino-tetrahydronaphthalenes;

2,5-diamino-tetrahydronaphthalenes; and

3,4-diamino-tetrahydronaphthalenes; and

combinations thereof; and

wherein the golf ball has a coefficient of restitution of 0.7 or greater.

2. The golf ball of claim 1, wherein the core is a solid core having a compression of 40 to 100 or a coefficient of restitution of 0.7 or greater, and the layer has a flexural modulus of 1,000 psi to 100,000 psi or a Shore D hardness of 90 or less.

3. The golf ball of claim 1, wherein the golf ball further comprises:

an intermediate layer disposed between the at least one layer and the core;

or an outer cover layer disposed about the at least one layer.
