ABSTRACT:
A golf ball comprising a substantially spherical homogeneous molded mass of elastomer highly cross-linked into a three dimensional network with long, flexible cross-links formed from a metal-containing cross-linkable monomer, said comonomer simultaneously functioning at least in part as a filler, said mass exhibiting substantially isometric compression across any diameter. Advantageously the elastomer comprises polybutadiene and said metal-containing cross-linkable monomer comprises zinc dimethacrylate present in about 15 to 60 parts per 100 parts by weight of the polybutadiene. The composition may additionally contain a small amount of zinc oxide. By proper selection of the shape and make up of the slugs from which the balls are molded or by particular techniques, e.g. laboratory sheeting mills, balls can be produced which have a maximum difference in compression across different diameters of about 5 units.
