ABSTRACT:
In a homogeneous molded golf ball comprising a filled elastomer highly cross-linked into a three dimensional network with long, flexible cross-links formed of a polymerized cross-linking monomer, the improvement which comprises using as said cross-linking monomer a metal-containing cross-linkable monomer whereby said comonomer simultaneously functions as said filler at least in part. The preferred elastomer is cis-polybutadiene. The metal-containing cross-linkable monomer can be formed in situ or added as such and preferably comprises a salt of at least one metal selected from the group consisting of zinc, magnesium and calcium, and at least one acid selected from the group consisting of methacrylic, acrylic, cinnamic, acotinic, crotonic, vinylacetic, itaconic, styrenesulfonic and benzoylacrylic acids. Additional filler may be added to adjust the density to the desired value. The composition is preferably preheated prior to molding and produces golf balls of superior properties with respect to durability, cannon life, sound and distance properties.
