Abstract
A golf ball including a thermoplastic inner core and a thermoset outer core layer is described. The inner core has a surface hardness of 43 to about 65 Shore D and a center hardness of about 30 to 43 Shore D that is less than the surface hardness to define a positive hardness gradient. A cover includes an inner and outer cover layer. The thermoplastic inner core is formed from a highly-neutralized ionomer comprising a copolymer of ethylene and an α,β-unsaturated carboxylic acid, an organic acid or salt thereof, and sufficient cation source to fully-neutralize the acid groups of the copolymer by 80% or greater. The outer core layer includes a polybutadiene rubber and has a surface hardness greater than an interior hardness by about 6 to 11 Shore D points to define a shallow positive hardness gradient.
