Abstract: Multi-layered golf balls containing a dual-core structure are provided. The core structure includes an inner core (center) comprising a thermoplastic composition, preferably including: a) ethylene acid copolymer, b) plasticizer, and c) cation source. Preferably, a fatty acid ester such as ethyl oleate is used as the plasticizer. The outer core layer is preferably formed from a thermoset composition such as polybutadiene rubber. The core layers have different hardness levels. The core assembly preferably has a positive hardness gradient extending across the entire assembly. The core structure and resulting ball have relatively good resiliency at given compressions.

Abstract: The present invention is directed to a golf ball having a cover in which the dimples have two distinct hardness regions. The cover of the present invention is formed from a castable formulation including at least one prepolymer that incorporates some degree of unsaturation in the backbone of the polymer, at least one curative, and at least one free radical initiator. The present invention also explores the methods of making such golf balls. The methods of the present invention allow for the production of a golf ball dimple with two distinct hardnesses to be formed using a single castable formulation.

Abstract: A golf ball includes a unitary core having an outer surface, a geometric center, and a soft transition region adjacent to the outer surface, and is formed from a substantially homogenous composition. The ball further includes an outer cover layer. The soft transition region has a thickness of up to 4 mm, has about 8 to 20 percent trans-polybutadiene isomer, and has a negative hardness gradient of up to 15 Shore C. The core has an overall negative hardness gradient of up to 20 Shore C and has a gradient quotient, GQ, defined by the equation: G + T 10 × COR ≤ 7 where G is the overall negative hardness gradient in Shore C, T is the percent of trans-polybutadiene isomer at the core outer surface, and COR is the coefficient of restitution measured at an incoming velocity of 125 ft/s.
