Abstract:
1. A golf ball comprising a cover and a core, said core comprising a) an acid copolymer of the composition E/X/Y wherein E represents copolymerized residues of ethylene, X represents copolymerized residues of an α,β ethylenically unsaturated carboxylic acid, and Y represents copolymerized residues of a C b) about 10 to about 45 wt. % of a high molecular weight, monomeric organic acid or salt thereof based on total weight of components a), b), and c) provided that component (b) does not exceed 50 wt. % of (a) plus (b); c) about 1 to about 35 wt. % of a thermoplastic resin; d) a cation source present at a level sufficient to neutralize 95 to 110% of the combined acid content of components a) and b); and e) zero to about 60 wt. % of a filler based on weight of components a) plus b) plus c) plus e); wherein the filler (e) is present in a type and amount sufficient to achieve a density between the density of the composition without filler and 1.8 grams per cubic centimeter; and wherein the core has a dimple pattern such that when positioned in the ball and covered by the cover having a dimple pattern, the cover thickness in the dimple areas is the about the same as the cover thickness in the non-dimpled areas.
