Golf ball forming compositions comprising polyamide blended with sulfonated or phosphonated polymers
First Claim
1. A golf ball comprising a cover and a core, wherein the cover is formed of a composition which comprises a blend of from about 1 wt. % to about 99 wt. % of at least one polyamide polymer and from about 99 wt. % to about 1 wt. % of at least one sulfonated and/or phosphonated polymer selected from the group consisting of sulfonated polymers, phosphonated polymers, sulfonated and phosphonated polymers, and mixtures thereof.

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 polyamide, in the form of a homopolymer, a copolymer or mixtures thereof. The compositions include a blend of about 1 wt. % to about 99 wt. % of at least one sulfonated and/or phosphonated polymer and about 99 wt. % to about 1 wt. % of at least one polyamide polymer. The polyamides of the present invention comprise polyamides and polyamide copolymers, such as polyamide block copolymers. The sulfonated and/or phosphonated polymer preferably comprises sulfonated thermoplastic elastomers, sulfonated thermoplastic polymers, and mixtures thereof. The present invention is further directed to a method of making a golf ball core, an intermediate layer or a cover composition, comprising blending one or more sulfonated and/or phosphonated polymers and one or more polyamides or polyamide copolymers such that there is mixing of the different polymeric components to give a blend suitable for forming into the above golf ball components.
