Abstract
A golf ball () in accordance with the principles of the present invention has a core () with a low compression, but has at least two additional layers () that provide for increased durability and control. The core () is formed of a polybutadiene compound that produces a zero (or less) compression. The mantle () is molded around the core () using terpolymers, which are comprised of ethylene, acrylic acid and n-butyl acrylate, with 100% of the acrylic acid groups neutralized with metal ions. The mantle (), when molded, yields a deflection of greater than 0.170 inches under an applied static load of 200 lb. This correlates to a PGA compression of between about −20 and 15. The cover () is molded using conventional ionomers and 'very low modulus' ionomers (V.L.M.I.), and has a hardness of between about 50 and 75 on a Shore D scale.
