A golf ball comprising a core and a cover, wherein the core consists of: a solid inner core layer formed from a plasticized non-acid polymer composition PC p/N-A and having a diameter of 1.10 inch or less and a center Shore C hardness (H center ) of 50 or less, one or more optional intermediate core layers, and an outer core layer formed from at least one of a thermoset rubber composition TR and a thermoplastic composition TP and having a thickness of 0.200 inches or greater and an outer surface Shore C hardness (H outer surface ) of 70 or greater, wherein H outer surface >H center , and H outer surface −H center ≧40. In another embodiment, the center Shore C hardness (H center ) is 40 or less, the outer surface Shore C hardness (H outer surface ) is 85 or greater, and H outer surface −H center ≧45. In one embodiment, an intermediate layer is disposed between the outer core layer and the cover. The plasticized non-acid polymer composition PC p/N-A . may be formed from at least one non-acid polymer composition and at least one plasticizer. |
