Abstract
A golf ball comprising a core included of a polymer containing an acid group fully-neutralized by an organic acid or a salt, a cation source, or a suitable base thereof, the core having a first Shore D hardness, a compression of no greater than about 90, and a diameter of between about 1.00 inches and about 1.64 inches; and a cover comprising a polyurea formed from a polyisocyanate, a polyamine, and a curing agent; wherein the ball has a compression of between about 50 and about 120.
Claims38
A golf ball comprising:
- a core comprised of a polymer containing an acid group fully-neutralized by an organic acid or a salt, a cation source, or a suitable base thereof, the core having a first Shore D hardness, a compression of no greater than about 90, and a diameter of between about 1.00 inches and about 1.64 inches;
- and
- a cover comprising a polyurea formed from a polyisocyanate, a polyamine, and a curing agent;
- wherein the ball has a compression of between about 50 and about 120.
1 more element
A golf ball comprising:
- a core comprised of a polymer containing an acid group neutralized by an organic acid or a salt, cation source, or a suitable base thereof being present in an amount sufficient 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 90, 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 comprising polyurea, the layer 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;
- and the ball has a compression of between about 50 and about 120.

A golf ball comprising:
- a core comprising a solid center and an outer core layer, the core having a first Shore D hardness, a compression of no greater than about 90, and a diameter of between about 1.00 inches and about 1.64 inches;
- and
- a first cover layer comprising a polyurea formed from a polyisocyanate, a polyamine, and a curing agent;
- wherein at least one of the solid center or the outer core layer comprises a polymer containing an acid group fully-neutralized by an organic acid or a salt, a cation source, or a suitable base thereof;
