    摘要： A golf ball containing a layer, which comprises nanosheets of exfoliated graphite dispersed in a polymeric matrix, is provided. Exfoliated graphite is graphite that has been intercalated preferably by an oxidation process, where the atoms or molecules have been inserted into the inter-planar spacing between the layered planes of carbons, and expanded. The intercalated graphite is expanded or exfoliated preferably by brief exposure to high heat to expand the thickness of the graphite. The expanded or exfoliated graphite is then mixed with monomers and polymerized in situ to form a polymer with a network of nanosheets of the exfoliated graphite dispersed therein. The exfoliated graphite advantageously retains its nanostructure during the polymerization process. The resulting golf ball layer comprising such polymer with nanosheets of exfoliated graphite exhibits superior tensile strength, low permeability to gas and increased impact strength. A golf ball comprising a water vapor barrier layer, wherein the water vapor barrier layer comprises a foil of compressed exfoliated graphite layer, is also provided. The expanded or exfoliated graphite is compressed together into flexible thin sheets or foils. Such sheets may also be made with a polymeric binder.

    摘要： A long distance, low initial spin golf ball is disclosed. The golf ball includes a high moment of inertia core assembly, which may comprise a low specific gravity core and an optional intermediate layer. This sub-assembly is encased within a high specific gravity cover with Shore D hardness in the range of about 40 to about 80. The core is preferably made from a highly neutralized thermoplastic polymer with its specific gravity reduced, and the cover preferably has high specific gravity fillers dispersed therein. The cover is preferably made from thermoset polyurethane or polyurea.

    摘要： A golf ball comprising an inner core formed from a substantially homogenous composition such that the geometric center hardness is 56-80 Shore C and the outer surface hardness is 50-75 Shore C. An outer core layer has an outer surface having hardness of 85-98 Shore C and an inner surface hardness of 68-78 Shore C and being formed from a second homogenous rubber composition. A cover layer is disposed about the outer core layer. The hardness of the second outer surface is greater than the hardness of the inner surface to define a positive hardness gradient of +7 to +30 Shore C, and the hardness of the first outer surface is lower than the hardness of the geometric center to define a negative hardness gradient of −1 to −15 Shore C.
