Abstract
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 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.
Claims36
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 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.
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 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.
