The present invention is directed towards a multi-layer golf ball which comprises a core with one or more layers; at least one cover layer; and one or more mantle layers disposed between the core and cover layer, wherein the mantle layer comprises thermoplastic polyetherester, thermoplastic polyesterester dynamically vulcanized thermoplastic elastomer, functionalized styrene-butadiene elastomer, thermoplastic polyurethane, metallocene polymer or blends thereof and thermoset materials. Further, the present invention is directed to a ball having a core, a coverlayer and a mantle layer therebetween wherein the mantle layer has a flex modulus of less than 10,000 psi and the cover has a flex modulus greater than 80,000 psi. |

DETAILED DESCRIPTION The present invention is directed towards a multi-layer golf ball which provides a soft feel similar to a conventional wound ball, while also providing the distance, durability and relative ease of manufacturing of a conventional two piece ball.
The present invention is further directed towards a multi-layer golf ball which comprises a core with one or more layers; at least one cover layer; and one or more mantle layers disposed between the core and cover layer, wherein the mantle layer comprises thermoplastic polyetherester, thermoplastic polyetheramide, dynamically vulcanized thermoplastic elastomer, functionalized styrene-butadiene elastomer, thermoplastic polyurethane, metallocene polymer, or blends thereof and/or thermoset materials.
In a preferred embodiment, the present invention is also directed towards a multi-layer golf ball which comprises a core; a cover layer comprising an inner layer and an outer layer, wherein the outer layer comprises a material with a lower melting point or heat of reaction temperature (also referred to as cure temperature) than that of the material of the inner layer; and at least one mantle layer disposed between the core and cover layer, wherein the mantle layer comprises thermoplastic polyetherester, thermoplastic polyetheramide, dynamically vulcanized thermoplastic elastomer, functionalized styrene-butadiene elastomer, thermoplastic polyurethane or metallocene polymer and blends thereof.
The present invention is still further directed to a multi-layer golf ball which comprises a core, at least one cover layer and at least one mantle layer disposed between the core and cover layer wherein properties such as the thickness, hardness, flexural modulus, tensile modulus or Bayshore resilience of the various layers is such as to provide a ball with optimum performance characteristics.
