Patent Images
1. A golf ball comprising:
- a single layer core comprised of a polymer containing an acid group, an organic acid or salt, and sufficient a cation source, or a suitable base thereof to fully neutralize the acid groups of the polymer, the core having a first Shore D hardness, a compression of no greater than about 80, and a diameter of no less than about 1.53 inches; and
a cover formed of a blend comprising polyurethanes and polyureas or a copolymer comprising urethane and urea segments.

27. A golf ball comprising:
-
a single layer core comprised of a polymer containing an acid group, an organic acid or salt, and sufficient, cation source, or a suitable base present in an amount to neutralize the polymer by at least about 80%, wherein the core has a first Shore D hardness, a compression of no greater than about 80, and a diameter of about 0.5 to 1.55 inches; and
at least one cover layer disposed over the core having a material hardness of about 70 Shore D or less and formed of a blend comprising polyurethanes and polyureas, the blend having a second Shore D hardness being at least 10 points less than the first hardness and comprising at least one of pigments;
TiO2;
ZnO;
optical brighteners;
surfactants;
processing aids;
foaming agents;
density-controlling fillers;
UV stabilizers;
or light stabilizers. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)
