Abstract:
A golf ball comprising a cover having a thickness of at least about 0.03 inch and at least about 60 percent dimple coverage, a core having a PGA compression of at least about 40, and, optionally, a mantle situated between the cover and the core, wherein at least one of the cover, the core, and the mantle comprises at least one layer formed of a single-site catalyzed polymer blend comprising from about 1 to about 100 phr of at least one non-metallocene single-site catalyzed polymer having a hardness of at least about 15 Shore A, a flexural modulus of at least about 500 psi, a specific gravity of at least about 0.7, a dynamic shear storage modulus at 23.degree. C. of at least about 104 dynes/Cm.sup.2, and a loss tangent of no more than about 1, and from about 99 to 0 phr of at least one ionomer, non-ionomeric polymer, thermoset polymer, thermoplastic, or non-single-site catalyzed polymer, having a flexural modulus of at least about 500 psi, wherein the golf ball has a PGA compression of at least about 50.
