Abstract
The present invention relates to a golf ball, comprising a cover, a core and optional intermediate layers, wherein the various ball components are formed from compositions comprising a sulfonated and/or phosphonated ionomer. The sulfonated and/or phosphonated ionomer preferably comprises sulfonated thermoplastic elastomers, sulfonated thermoplastic polymers, sulfonated thermoset polymers and mixtures thereof. The compositions include a blend of about 1 wt. % to about 99 wt. % of at least one sulfonated and/or phosphonated ionomer and about 99 wt. % to about 1 wt. % of at least co-component polymer. The co-component polymer may be a conventional ionomer, a thermoplastic, a thermoplastic elastomer, a thermoset polymer or mixtures thereof.
