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 substantially optical brightener-free blend of about 1 wt. % to about 99 wt. % of at least one nonionomer 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 nylons, nylon copolymers and nylon block copolymers. The nonionomer polymer comprises a nonionomer thermoplastic elastomer or a nonionomer thermoplastic. The present invention also relates to a golf ball comprising a cover layer, a core and at least one intermediate layer interposed between the cover layer and the core, wherein one of said layers comprises a substantially optical brightener-free composition comprising from about 1 wt. % to about 99 wt. % of at least one nonionomer polymer and about 99 wt. % to about 1 wt. % of at least one polyamide polymer, and wherein an other one of said layers comprises a thermoset polymer. 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 nonionomer 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.
