Patent ID: 7358320

Claim:
A golf ball comprising: a core, the core having a first coefficient of restitution of 0.8 or greater at 125 ft/s; and at least one layer disposed about the core, the layer comprising a polyurea formed from a fluorinated polyamine, wherein the golf ball has a second coefficient of restitution of 0.8 or greater at 125 ft/s and the fluorinated polyamine comprises a branch-fluorinated polyamine comprising at least one monomeric unit of the structure: where R f ′ is the same or different monovalent linear or branched radicals of C 1-20 perfluoroalkyls, C 1-20 ω-hydroperfluoroalkyls, or C 4-60 oxaperfluorinated polyethers; Z is the same or different radicals of—O—, —S—, —NR—, —SO 2 —, or —N(R)SO 2 —; R is the same or different radicals of H or linear or branched C 1-6 alkyls; p is 1 when q is 1, or 0 when q is 2; and x is the same or different integers of 1 to 10.
