Abstract:
A golf ball having a coefficient of restitution of greater than about 0.7 and a compression of at least about 50 comprising a core and a cover disposed concentrically about the core with the cover having a thickness of at least about 0.03 inches and at least about 60 percent dimple coverage, wherein at least one of the cover and the core is formed of an ion-containing polymer composition comprising at least one of an ionene or a zwitter-ion polymer, wherein the ion-containing polymer composition has a flexural modulus from about 500 psi to 300,000 psi, a hardness of at least about 15 Shore A, a loss tangent of less than about 1 at about 23.degree. C., a specific gravity of at least about 0.7, and a dynamic shear storage modulus of at least about 10,000 dyn/cm.sup.2 at about 23.degree. C. and about 1 Hz.
