Abstract
The invention provides a golf ball having a cover, intermediate layers and/or a core comprising in whole or in part of water resistant polyurethane elastomers. The polyurethane elastomers may be blended with conventional materials employed to form golf balls, covers and intermediate layers.
Claims28
A golf ball comprising at least one cover layer wherein at least one said cover layer is formed from a composition comprising at least one polyurethane containing a hydrophobic backbone, said cover layer having a thickness of from about 0.02 inch to about 0.35 inch, a hardness of at least about 40 Shore D, a specific gravity of at least about 0.7, a flexural modulus of at least about 500 psi and at least about 60 percent dimple coverage, said golf ball having an Atti compression of from about 55 to about 120.
A golf ball comprising a cover, a core and at least one intermediate layer interposed between the cover and the core, wherein the intermediate layer is formed from a composition comprising at least one polyurethane containing a hydrophobic backbone.
A golf ball comprising a cover, a core and at least one intermediate layer interposed between the cover and the core, wherein the core is formed from a composition comprising at least one polyurethane containing a hydrophobic backbone.
