THERMOPLASTIC CORE HAVING A NEGATIVE HARDNESS GRADIENT FORMED FROM A PLASTICIZER-BASED GRADIENT-INITIATING SOLUTION |
摘要 |
A golf ball comprising a thermoplastic core, the core having an outer diameter of 1.51 inches to 1.59 inches and having an outer surface and a geometric center, each having a hardness; an outer cover layer; and an inner cover layer disposed between the core and the outer cover layer; wherein the hardness of the outer surface is less than the hardness of the geometric center to define a "negative" hardness gradient of 5 Shore C or greater.
