Abstract

A golf ball core, mantle, and/or cover layer(s) of golf ball having a composition comprising functionalized aluminosilicate particles having a particle size of less than 50 μm is disclosed herein. The aluminosilicate microspheres with an average diameter less than 50 μm are functionalized with, but not limited to, polysulfide, vinyl, amino, epoxy, hydroxyl, carboxyl, methacryloyl, hydrocarbon, mercapto and isocyanate.

Claims (21)

1. A golf ball comprising:

an inner core;

an outer core disposed over the inner core;

an inner mantle layer disposed over the outer core;

an outer mantle layer disposed over the inner mantle layer; and

a cover layer disposed over the outer mantle layer;

wherein at least one of the inner core, the outer core, the inner mantle layer, the outer mantle layer or the cover layer comprises a plurality of functionalized aluminosilicate microspheres, wherein each of the plurality of aluminosilicate microspheres has an average diameter less than 50 μm and each is functionalized with a mercapto.

2. A golf ball comprising:

an inner core;

an outer core disposed over the inner core;

an inner mantle layer disposed over the outer core;

an outer mantle layer disposed over the inner mantle layer; and

a cover layer disposed over the outer mantle layer;

wherein at least one of the inner core, the outer core, the inner mantle layer, the outer mantle layer or the cover layer comprises a plurality of functionalized aluminosilicate microspheres, wherein each of the plurality of aluminosilicate microspheres has an average diameter less than 50 μm and each is functionalized with an isocycanate.

3. A golf ball comprising:

an inner core;

an outer core disposed over the inner core;

an inner mantle layer disposed over the outer core;

an outer mantle layer disposed over the inner mantle layer; and

a cover layer disposed over the outer mantle layer;

wherein at least one of the inner core, the outer core, the inner mantle layer, the outer mantle layer or the cover layer comprises a plurality of functionalized aluminosilicate microspheres, wherein each of the plurality of aluminosilicate microspheres has an average diameter less than 50 μm and each is functionalized with an epoxy.
