Patent ID: 7208546

Claim:
A method for making a golf ball comprising the steps of: providing a core; providing a nanoparticulate; providing a first monomer comprising an olefin; providing a second monomer comprising an α,β-ethylenically unsaturated carboxylic acid; in-situ polymerizing the first monomer and the second monomer in the presence of the nanoparticulate to form a nanocomposite non-ionic co-polymer, the nanoparticulate consisting essentially of carbon nanotubes; fullerenes; single-wall and multi-wall carbon nanotubes; carbon nanofibrils; glass ionomers; resin-modified glass ionomers; silicon ionomers; lipid-based nanotubules, graphite sheets, or polyhedral oligomeric silsequioxanes; forming an inner cover layer about the core from the nanocomposite non-ionic polymer; and forming an outer cover layer over the inner cover layer, the outer cover comprising a castable urethane or urea material.
