Abstract:
A golf ball comprising a cover and a core layer, wherein the cover is formed of a composition consisting essentially of at least one ionomer formed from a polymer having moieties selected from the group consisting of sulfonate, phosphonate and mixtures thereof, and wherein the polymer is a thermoplastic polymer and comprises at least one of polyolefins, polycarbonates, polyamides, polyphenylene oxides, imidized, amino group containing polymers, polyether ketones, polysulfones, poly(phenylene sulfide), poly(ether imide), reinforced engineering plastics, poly(N-octadecylacrylamide), poly(octadecyl methacrylate), poly(ethylene oxide), poly(oxymethylene), poly(silazane), poly(fiuran tetracarboxylic acid diimide), poly(acrylonitrile), poly(alkyl)alkylacrylates, polyesters, poly(styrene), poly(.alpha.-methylstyrene), poly(4-dodecylstyrene), poly(4-tetradecylstyrene), acrylic-styrene-acrylonitrile copolymer, acrylonitrile-butadiene-styrene copolymer, high impact polystyrene, a copolymer consisting essentially of a styrene or an .alpha.-alkyl styrene monomer, a vinyloxazoline or a 1-alkyl vinyloxazoline monomer, wherein the alkyl groups range, independently from methyl to decyl inclusive and may be linear or branched, a terpolymer consisting essentially of a styrene or an .alpha.-alkyl stene monomer, an alkyl acrylate or an alkyl alkylacrylate monomer, or a vinyloxazoline or a 1-alkyl vinyloxazoline monomer, wherein the alkyl groups range, independently, from methyl to decyl inclusive and may be linear or branched and the sulfonated thermoplastic polymer contains from about 0.1 mol % to about 30 mol % sulfonate moieties.
